Blocks the execution of the current thread forat least until theTIME_UTC based duration pointed to byduration has elapsed.

The sleep may resume earlier if asignal that is not ignored is received. In such case, ifremaining is notNULL, the remaining time duration is stored into the object pointed to byremaining.

[edit]Parameters

[edit]Return value

​0​ on successful sleep,-1 if a signal occurred, other negative value if an error occurred.

[edit]Notes

duration andremaining may point at the same object, which simplifies re-running the function after a signal.

The actual sleep time may be longer than requested because it is rounded up to the timer granularity and because of scheduling and context switching overhead.

The POSIX equivalent of this function isnanosleep.

[edit]Example

#include <threads.h>#include <time.h>#include <stdio.h> int main(void){printf("Time: %s",ctime(&(time_t){time(NULL)}));    thrd_sleep(&(struct timespec){.tv_sec=1},NULL);// sleep 1 secprintf("Time: %s",ctime(&(time_t){time(NULL)}));}
