Chapter 58: Multithreading

In C11 there is a standard thread library, <threads.h>, but no known compiler that yet implements it. Thus, to use multithreading in C you must use platform specific implementations such as the POSIX threads library (often referred to as pthreads) using the pthread.h header.

Section 58.1: C11 Threads simple example

#include <threads.h>

#include <stdio.h>

int run(void *arg)

{

printf(“Hello  world  of  C11  threads.”);

return  0;

}

int main(int argc, const char *argv[])

{

thrd_t thread;

int result;

thrd_create(&thread,  run,  NULL);

thrd_join(&thread,  &result);

printf(“Thread  return  %d  at  the  end\n“,  result);

}
