Defined in header
int thrd_sleep( const struct timespec* time_point,
struct timespec* remaining );
Blocks the execution of the current thread for at least until the TIME_UTC based time point pointed to by
time_point has been reached.
The sleep may resume earlier if a signal that is not ignored is received. In such case, if
remaining is not NULL, the remaining time duration is stored into the object pointed to by
|time_point||-||pointer to the time point to sleep until|
|remaining||-||pointer to the object to put the remaining time on interruption. May be NULL, in which case it is ignored|
 Return value
0 on successful sleep, -1 if an interrupt occurred, other negative value if an error occurred.
