Hello everyone,
It is with great honor that I bring you the C11-conforming header for thread
support of mcfgthread, c11thread.h:
https://github.com/lhmouse/mcfgthread/blob/master/src/env/c11thread.h
All headers in the mcfgthread project have been put into the public domain.
As JonY suggested a few days ago, it would be nice for mingw-w64 to have C11
thread support.
This announcement is not only a call for testers, but also a proposal for a C11
header for mingw-w64. We can have both C11 and C++11 threads from today.
The following code illustrates how to use C11 threads:
```
E:\Desktop>expand -t4 test.c
#include <mcfgthread/c11thread.h>
#include <stdio.h>
#include <stdlib.h>
int thread_proc(void *param){
printf("thread running: tid = %u, param = %p\n", (unsigned)thrd_current(),
param);
for(int i = 0; i < 5; ++i){
printf("thread going to sleep for one second...\n");
struct timespec ts;
ts.tv_sec = 1;
ts.tv_nsec = 0;
thrd_sleep(&ts, 0);
}
int exit_code = 67890;
printf("thread exiting: exit_code = %d\n", exit_code);
return exit_code;
}
int main(){
thrd_t tid;
int err;
if((err = thrd_create(&tid, &thread_proc, (void *)0x12345)) !=
thrd_success){
printf("thrd_create() returned %d\n", err);
abort();
}
printf("created thread: tid = %u\n", (unsigned)tid);
int exit_code;
if((err = thrd_join(tid, &exit_code)) != thrd_success){
printf("thrd_join() returned %d\n", err);
abort();
}
printf("joined thread: exit_code = %d\n", exit_code);
}
E:\Desktop>gcc test.c -std=c11 -Wall -Wextra -pedantic -lmcfgthread
E:\Desktop>a.exe
created thread: tid = 9876
thread running: tid = 9876, param = 00012345
thread going to sleep for one second...
thread going to sleep for one second...
thread going to sleep for one second...
thread going to sleep for one second...
thread going to sleep for one second...
thread exiting: exit_code = 67890
joined thread: exit_code = 67890
E:\Desktop>
```
In order to use C++11 std::thread (as well as std::mutex,
std::condition_variable, etc) you must rebuild GCC and its libraries.
