timers and timeline

Overview

Timer and Timeline Utils for C

Build Status Build status Codacy Badge

This library provides an easy way to set timers and timeouts. As initial version all timers run in single runloop at seperate thread. Currently only one thread is used for all timers, because there is only one runloop. In the future multiple runloop may be allowed.

Documentation

Currently all docs can be found in headers but in the future complete docs will be published.

Javascript and Swift/Objective-C like API

setTimeout in javascript is very useful and it is now in C:

tm_settimeout(callback, arg, delay);

TODOs:

  • Improve loopkup, make timers ordered. This may reduce some lookup operations runloop
  • Tests
  • More time and timeline utils
  • More platform support

Build

Unix (Autotools)

$ sh autogen.sh
$ ./configure
$ make
$ [sudo] make install

you can grap library in .libs folder after build finished

Windows (MSBuild)

Windows related build files, project files are located in win folder, make sure you are inside tm/win folder. Code Analysis are enabled, it may take awhile to build

$ cd win
$ .\build.bat

Example usage

#include <tm/tm.h>

/* callback */
void
mytimer(tm_timer *timer) {
  printf("my timer\n");
}

void
delayed_func(void *arg) {
  printf("settimeout: %s\n", (const char *)arg);
}

int 
main(int argc, const char * argv[]) {
  tm_timer   *timer1, *timer2, *timer3;
  tm_interval start, end, elapsed;
 
  /* option 1: alloc timer and start */
  timer1 = tm_alloc(mytimer, 1.5); /* 1.5 seconds */
  tm_start(timer1);
  
  /* option 2: alloc timer and start with delay */
  timer2 = tm_alloc(mytimer, 1.5); /* 1.5 seconds */
  tm_start_at(timer2, 0.05);       /* start after 0.05 secons */
  
  /* option 3: alloc timer and start with delay */
  timer3 = tm_schedule(mytimer, 1.5, 0.05); /* same as tm_alloc + tm_start_at */
  
  /* option 4: javascript-like setTimeout */
  tm_settimeout(delayed_func, "Hello World!", 0.00001);
  
  /*
  
  if we call free here timers will be stopped 
  
  tm_free(timer1);
  tm_free(timer2);
  tm_free(timer3);

  */
  
  /* measure elapsed time */
  start = tm_time();
  
  /* do stuff */
  
  end = tm_time();
  
  elapsed = end - start;
  
  /* wait timers to finish; otherwise main thread will cause timer thread to be exited */
  tm_wait();

  return 0;
}

Sqrt OS is a simulation of an OS scheduler and memory manager using different scheduling algorithms including Highest Priority First (non-preemptive), Shortest Remaining Time Next, and Round Robin.

A CPU scheduler determines an order for the execution of its scheduled processes; it decides which process will run according to a certain data structure that keeps track of the processes in the system and their status. A process, upon creation, has one of the three states: Running, Ready, Blocked (doing I/O, using other resources than CPU or waiting on unavailable resource).
