Hello I love this library , but I'm having issues with displaying my videos and downloads folder. I tried using a folder inside of them and it worked, but for some odd reason these folders are not displaying.

Any idea why?

Please note I built a wrapper class around TinyDir so that I can not have to call it often.

See http://pastebin.com/sS3UfDAw and http://pastebin.com/EwTEJsf6

It looks like readdir_r is not supported by MinGW-w64 distributions. When I try to build the samples on my MinGW Builds 5.3.0 compiler, I get the following errors.

In file included from tinydir\samples\file_open_sample.c:2:0:
tinydir/tinydir.h: In function 'tinydir_open':
tinydir/tinydir.h:194:10: error: implicit declaration of function 'readdir_r' [-Werror=implicit-function-declaration]

 #           error "buffer size for readdir_r cannot be determined"
             ^

Is there an alternative?

I was in need to browse directories in C. I find tinydir lib. But I need to get files extensions, so here is the code. I added a member to tinydir_file structure : (char *) extension. This member is filled with the pointer to the last dot find in the filename. Searching the last dot is made using the standard C function : strrchr()

Hi,

The following code crashes when compiled on MSVS2013 with debug version of C runtime lib:

#define UNICODE
#define _UNICODE
#include "tinydir.h"

int main() {
    tinydir_file fi;
    tinydir_file_open(&fi, L".");
    (void) fi;
    return 0;
}

Compilation command:

>cl test.c /MDd
Microsoft (R) C/C++ Optimizing Compiler Version 18.00.40629 for x86

I can see that something is wrong with this call - https://github.com/cxong/tinydir/blob/98e9a82dd4296db5f5445e1026cdf7ddd6121a73/tinydir.h#L625 but it is not clear what is wrong.

UNICODE is defined in my project. But I get the following errors.

Hello, the lib is fantastic. I am a newer in C language and I wonder how to implement it. Should I just include the header file tinydir.h ? But when I do this I cannot run the samples because there are many errors about strict type transforms. Should I do something more? Thank you.

In our repository idaholab/moose, we are getting the following warnings when compiling with gcc 11

Is this user error or is this something that can be fixed on your end? This is our user code

std::list<std::string>
listDir(const std::string path, bool files_only)
{
  std::list<std::string> files;

  tinydir_dir dir;
  dir.has_next = 0; // Avoid a garbage value in has_next (clang StaticAnalysis)                                       
  tinydir_open(&dir, path.c_str());

  while (dir.has_next)
  {
    tinydir_file file;
    file.is_dir = 0; // Avoid a garbage value in is_dir (clang StaticAnalysis)                                        
    tinydir_readfile(&dir, &file);

    if (!files_only || !file.is_dir)
      files.push_back(path + "/" + file.name);

    tinydir_next(&dir);
  }

  tinydir_close(&dir);

  return files;
}

Tinydir disable pragma warning in all file that include this header, I have fixed the bug, update the repo: before the line 41 add this:

# pragma warning(push)

before the last line ( last #endif ) add this;

#ifdef _MSC_VER
# pragma warning(pop)
#endif

Then pragma warning working in all files except tinydir.

Comment with : // Variable created here :'( , are just there because i don't like creating variable in the middle of a function in C (I prefer to put them only at the beginning).

I have a folder of 8000 images in it. If I call tinydir_open_sorted on it's path, it will take as long as 2 minutes to retrieve the full list of file. I am under MSVC 2010 under windows 7 x64. Profiling shows 99.9% of the time spent in an unknown method. If I use tinydir_open instead and I sort the file myself using a vector and std::sort, the result will take much less than a second to return.

I think the problem is with the use of realloc, that must constantly allocate new block of memory compare to a std::vector that might handle the reallocation much better.

Here's the C++ version that run much faster (to compare with tinydir_open_sorted) std::vectorstd::string dirList tinydir_open(&dir, dirPath.c_str()); while (dir.has_next) { tinydir_file file; tinydir_readfile(&dir, &file); if(!file.is_dir) dirList.push_back(std::string(file.name)); tinydir_next(&dir); }

tinydir_close(&dir); std::sort(dirList.begin(), dirList.end()); return dirList;

Hello,

I'm struggling to open the top directory on Windows (C:). Other directories are fine. For instance, when using file_open_sample.c I get:

C:\msys32\home\IEUser\tinydir>a.exe C:\
Error opening file: No error

C:\msys32\home\IEUser\tinydir>a.exe C:
Error opening file: No error

C:\msys32\home\IEUser\tinydir>a.exe "C:\Program Files"
Path: C:/Program Files
Name: Program Files
Extension:
Is dir? yes
Is regular file? no

i used MinGW here, but I think it's the same with MSVC. Am I missing something?

Hi, I was wondering if there's a possibility to have tinydir_open_sorted to have multiple sorting options. One way I can think of to achieve this would be to pass our own (comparator?) like this one https://github.com/cxong/tinydir/blob/master/tinydir.h#L755

This would allow the user to sort alphabetically in both ascending/descending order as well sorting by size, timestamps etc.

I.e. a file, which you could create with

ln -s /broken/link .

In that case iterate_sample.c shows directory listing only partially. And random_access_sample.c fails to open a directory at line 8.

tinydir_readfile finishes at line 559 when processing a broken link

My OS is Linux.

In tinydir_open_sorted, a first pass is used to count the number of files, then a second pass actually reads the file info. In between the two passes, tinydir closes and reopens the dir.

This is unnecessary with dirent; there's the rewinddir function which allows going back to the first file. This would also eliminate a race condition where the directory may have changed between the two passes.

Not sure if there's an equivalent for Windows.
