Modern C++ socket library.



Build Status

Simple, modern, C++ socket library.

This is a fairly low-level C++ wrapper around the Berkeley sockets library using socket, acceptor, and connector classes that are familiar concepts from other languages.

The base socket class wraps a system socket handle, and maintains its lifetime. When the C++ object goes out of scope, it closes the underlying socket handle. Socket objects are generally moveable but not copyable. A socket can be transferred from one scope (or thread) to another using std::move().

Currently supports: IPv4, IPv6, and Unix-Domain Sockets on Linux, Mac, and Windows. Other *nix and POSIX systems should work with little or no modification.

All code in the library lives within the sockpp C++ namespace.

Latest News

The library is reaching a stable API, and is on track for a 1.0 release in the near future. Until then, there may be a few more breaking changes, but hopefully those will be fewer than we have seen so far.

On that note, despite being recently refactored and re-versioned at 0.x, earlier implementations of this library have been in use on production systems since ~2003, particularly with remote embedded Linux data loggers. Things that we now call IoT gateways and edge devices. It can be counted on to be reliable.

Unreleased Features in this Branch

The following updates exist in this branch in the repository, but have yet to be formally released:

  • [#37] socket::get_option() not returning length on Windows.
  • [#39] Using SSIZE_T for ssize_t in Windows
  • Now acceptor::open() uses the SO_REUSEPORT option instead of SO_REUSEADDR on non-Windows systenms. Also made reuse optional.

New in v0.7

This release mainly targeted bug fixes, API inconsistencies, and numerous small features that had been overlooked previously.

  • Base socket class
    • shutdown() added
    • create() added
    • bind() moved into base socket (from acceptor)
  • Unix-domain socket pairs (stream and datagram)
  • Non-blocking I/O
  • Scatter/Gather I/O
  • stream_socket cloning.
  • Set and get socket options using template types.
  • stream_socket::read_n() and write_n() now properly handle EINTR return.
  • to_timeval() can convert from any std::chrono::duration type.
  • socket::close() and shutdown() check for errors, set last error, and return a bool.
  • tcpechomt.cpp: Example of a client sharing a socket between read and write threads - using clone().
  • Windows enhancements:
    • Implemented socket timeouts on Windows
    • Fixed bug in Windows socket cloning.
    • Fixed bug in Windows socket::last_error_string.
    • Unit tests working on Windows
  • More unit tests


Contributions are accepted and appreciated. New and unstable work is done in the develop branch Please submit all pull requests against that branch, not master.

For more information, refer to:


  • Unit Tests - The framework for unit and regression tests is in place (using Catch2), along with the GitHub Travis CI integration. But the library could use a lot more tests.
  • Consolidate Header Files - The last round of refactoring left a large number of header files with a single line of code in each. This may be OK, in that it separates all the protocols and families, but seems a waste of space.
  • Secure Sockets - It would be extremely handy to have support for SSL/TLS built right into the library as an optional feature.
  • SCTP - The SCTP protocol never caught on, but it seems intriguing, and might be nice to have in the library for experimentation, if not for some internal applications.

Building the Library

CMake is the supported build system.


  • A conforming C++-14 compiler.
    • gcc v5.0 or later (or) clang v3.8 or later.
    • Visual Studio 2015, or later on WIndows.
  • CMake v3.5 or newer.
  • Doxygen (optional) to generate API docs.
  • Catch2 (optional) to build and run unit tests.

Build like this on Linux:

$ cd sockpp
$ mkdir build ; cd build
$ cmake ..
$ make
$ sudo make install

Build Options

The library has several build options via CMake to choose between creating a static or shared (dynamic) library - or both. It also allows you to build the example options, and if Doxygen is

Variable Default Value Description
SOCKPP_BUILD_SHARED ON Whether to build the shared library
SOCKPP_BUILD_STATIC OFF Whether to build the static library
SOCKPP_BUILD_DOCUMENTATION OFF Create and install the HTML based API documentation (requires Doxygen)
SOCKPP_BUILD_EXAMPLES OFF Build example programs
SOCKPP_BUILD_TESTS OFF Build the unit tests (requires Catch2)

TCP Sockets

TCP and other "streaming" network applications are usually set up as either servers or clients. An acceptor is used to create a TCP/streaming server. It binds an address and listens on a known port to accept incoming connections. When a connection is accepted, a new, streaming socket is created. That new socket can be handled directly or moved to a thread (or thread pool) for processing.

Conversely, to create a TCP client, a connector object is created and connected to a server at a known address (typically host and socket). When connected, the socket is a streaming one which can be used to read and write, directly.

For IPv4 the tcp_acceptor and tcp_connector classes are used to create servers and clients, respectively. These use the inet_address class to specify endpoint addresses composed of a 32-bit host address and a 16-bit port number.

TCP Server: tcp_acceptor

The tcp_acceptor is used to set up a server and listen for incoming connections.

int16_t port = 12345;
sockpp::tcp_acceptor acc(port);

if (!acc)

// Accept a new client connection
sockpp::tcp_socket sock = acc.accept();

The acceptor normally sits in a loop accepting new connections, and passes them off to another process, thread, or thread pool to interact with the client. In standard C++, this could look like:

while (true) {
    // Accept a new client connection
    sockpp::tcp_socket sock = acc.accept();

    if (!sock) {
        cerr << "Error accepting incoming connection: "
            << acc.last_error_str() << endl;
    else {
        // Create a thread and transfer the new stream to it.
        thread thr(run_echo, std::move(sock));

The hazards of a thread-per-connection design is well documented, but the same technique can be used to pass the socket into a thread pool, if one is available.

See the tcpechosvr.cpp example.

TCP Client: tcp_connector

The TCP client is somewhat simpler in that a tcp_connector object is created and connected, then can be used to read and write data directly.

sockpp::tcp_connector conn;
int16_t port = 12345;

if (!conn.connect(sockpp::inet_address("localhost", port)))

conn.write_n("Hello", 5);

char buf[16];
ssize_t n =, sizeof(buf));

See the tcpecho.cpp example.

UDP Socket: udp_socket

UDP sockets can be used for connectionless communications:

sockpp::udp_socket sock;
sockpp::inet_address addr("localhost", 12345);

std::string msg("Hello there!");
sock.send_to(msg, addr);

sockpp::inet_address srcAddr;

char buf[16];
ssize_t n = sock.recv(buf, sizeof(buf), &srcAddr);

See the udpecho.cpp and udpechosvr.cpp examples.


The same style of connectors and acceptors can be used for TCP connections over IPv6 using the classes:


Examples are in the examples/tcp directory.

Unix Domain Sockets

The same is true for local connection on *nix systems that implement Unix Domain Sockets. For that use the classes:

unix_socket  (unix_stream_socket)

Examples are in the examples/unix directory.

Implementation Details

The socket class hierarchy is built upon a base socket class. Most simple applications will probably not use socket directly, but rather use top-level classes defined for a specific address family like tcp_connector and tcp_acceptor.

The socket objects keep a handle to an underlying OS socket handle and a cached value for the last error that occurred for that socket. The socket handle is typically an integer file descriptor, with values >=0 for open sockets, and -1 for an unopened or invalid socket. The value used for unopened sockets is defined as a constant, INVALID_SOCKET, although it usually doesn't need to be tested directly, as the object itself will evaluate to false if it's uninitialized or in an error state. A typical error check would be like this:

tcp_connector conn({"localhost", 12345});

if (!conn)
    cerr << conn.last_error_str() << std::endl;

The default constructors for each of the socket classes do nothing, and simply set the underlying handle to INVALID_SOCKET. They do not create a socket object. The call to actively connect a connector object or open an acceptor object will create an underlying OS socket and then perform the requested operation.

An application can generally perform most low-level operations with the library. Unconnected and unbound sockets can be created with the static create() function in most of the classes, and then manually bind and listen on those sockets.

The socket::handle() method exposes the underlying OS handle which can then be sent to any platform API call that is not exposed by the library.

Thread Safety

A socket object is not thread-safe. Applications that want to have multiple threads reading from a socket or writing to a socket should use some form of serialization, such as a std::mutex to protect access.

A socket can be moved from one thread to another safely. This is a common pattern for a server which uses one thread to accept incoming connections and then passes off the new socket to another thread or thread pool for handling. This can be done like:

sockpp::tcp6_socket sock = acc.accept(&peer);

// Create a thread and transfer the new socket to it.
std::thread thr(handle_connection, std::move(sock));

In this case, handle_connection would be a function that takes a socket by value, like:

void handle_connection(sockpp::tcp6_socket sock) { ... }

Since a socket can not be copied, the only choice would be to move the socket to a function like this.

It is a common patern, especially in client applications, to have one thread to read from a socket and another thread to write to the socket. In this case the underlying socket handle can be considered thread safe (one read thread and one write thread). But even in this scenario, a sockpp::socket object is still not thread-safe due especially to the cached error value. The write thread might see an error that happened on the read thread and visa versa.

The solution for this case is to use the socket::clone() method to make a copy of the socket. This will use the system's dup() function or similar create another socket with a duplicated copy of the socket handle. This has the added benefit that each copy of the socket can maintain an independent lifetime. The underlying socket will not be closed until both objects go out of scope.

sockpp::tcp_connector conn({host, port});

auto rdSock = conn.clone();
std::thread rdThr(read_thread_func, std::move(rdSock));

The socket::shutdown() method can be used to communicate the intent to close the socket from one of these objects to the other without needing another thread signaling mechanism.

See the tcpechomt.cpp example.

    Reasons for implementing `sock_address_ref`

    First off, thanks for writing sockcpp! It's almost exactly what I was looking for in a modernized C++ sockets library.

    I've been digging through the code, and I'm confused about why you've preferred to implement and use sock_address_refover using C++ references to sock_address.

  • Non-blocking I/O

    Non-blocking I/O

    It would be useful to support non-blocking I/O on sockets, and non-blocking connect and accept. This allows a lot more flexibility with threading, instead of having to devote one or two threads to every socket. It also seems like the only way to control the timeout of connect.

    I've implemented this and will try to put a PR together today.

  • last_error property is not thread-safe

    last_error property is not thread-safe

    The implementation of the socket class's last_error property is not thread-safe. The error code is copied from errno into a member variable after a system call. However, the error really needs to be tracked per thread, as errno itself is.

    This is significant because it's not uncommon to have one thread writing to a socket and another thread reading from it — this is a typical way to implement WebSockets, for example. What can happen in this case is:

    1. Thread A calls write.
    2. The underlying send system call fails, and the error is copied from errno into the socket's lastErr_.
    3. Thread B calls read.
    4. The underlying recv system call succeeds, so lastErr_ is set to 0.
    5. Thread A sees that the write call returned -1, and calls get_last_error.
    6. get_last_error returns 0, not the actual error from the write.

  • Get unit tests working on all platforms.

    Get unit tests working on all platforms.

    I was able to make it compile and run. The hardest part, actually, was fighting with CMake since Catch2 is not something I normally "install" since it's just one (or two) headers. Some CMake patching took care of that though, and the only thing left is the following issues (on Windows) in the unit tests causing 7 test and 8 assertion failures:

    • Incorrect assumption: Address information is available before socket connection (family type will remain unspecified, as opposed to the various checks for AF_INET)
    • Incorrect assumption: Windows uses POSIX error codes (e.g. sock.last_error() == EAFNOSUPPORT needs to be sock.last_error() == WSAEAFNOSUPPORT). Also, often these codes are WSAEINVAL or WSAENOTSOCK instead.
    • socket::pair not implemented for Windows, so its corresponding test fails
    • to_timeval is not implemented on Windows, causing compilation failures

    All of the above are pretty easily fixable though.

    EDIT OH I forgot, initialize() is never called during the tests so a lot of tests initially failed with the "not initialized" error. I fixed that by not auto generating the catch main function (GOTCHA: Include socket platform.h before catch.hpp to avoid odd errors from including headers in the wrong order)

    Doc-comment issues (Clang warnings with -Wdocumentation)

    There are a number of glitches in the doc-comments, especially @param directives, like name mismatches and empty descriptions. They're flagged as warnings by Doxygen, and by Clang if -Wdocumentation is on.

    Not a big deal, except that the project I work on builds with -Wdocumentation -Werror (because it's a library with its own API and doc-comments), so when I include sockpp headers they break the build.

    I can work around this by wrapping all the includes with #pragma clang diagnostic push / ignored / pop, but it's a pain and it'd be nice if these were cleaned up along with the other header-file work that's acknowledged in the README :)

  • Definition of ssize_t is wrong

    Definition of ssize_t is wrong

    sockpp has its own declaration of ssize_t in platform.h, but on non-Windows systems it defines it as int. ~~This is wrong on 64-bit OSs that use 32-bit ints, which includes all Apple platforms. (Dunno about Linux or BSD.) This leads to compile errors if a source file ends up including both platform.h and the OS's declaration. That aside, there are potentially actual integer overflow bugs if dealing with sizes > 4GB.~~

    You shouldn't need to declare this at all. Instead:

    • ~~On a POSIX-compliant OS, #include <sys/types.h>.~~
    • On Windows, #include <BaseTsd.h> and then using ssize_t = SSIZE_T;.

    (Also, it's kind of icky that the types declared in platform.h are all in the global namespace. Could they be put in the sockpp namespace like the rest of the API?)

    • Generic base classses are being re-implemented to use sock_address and sock_address_ref as generic addresses.
    • (Breaking change) In the socket class(es) the bool address(address&) and bool peer_address(addr&) forms of getting the socket addresses have been removed in favor of the ones that simply return the address. Added get_option() and set_option() methods to the base socketclass.
    • The GNU Make build system (Makefile) was deprecated and removed.
