sc/condition

Condition

Overview

• Condition wrapper for Posix and Windows.
• Normally, if no thread waits on a condition, signal is missed. This
  implementation differs as it will keep a result variable when 'signal' is
  called. Signal will mark the condition 'done'. When another thread calls
  wait(), it won't be blocked, it will return immediately with the user
  provided data.

Usage

#include "sc_cond.h"

#include <stdio.h>

int main()
{
    struct sc_cond cond;

    sc_cond_init(&cond); // Init once
    
    sc_cond_signal(&cond, "test"); // Call this on thread-1
    char* p = sc_cond_wait(&cond); // Call this on another thread.

    printf("%s \n", p); // Prints "test"
    
    sc_cond_term(&cond); // Destroy

    return 0;
}
