nanosleep(3c)

Standard C Library Functions                                     nanosleep(3C)



NAME
       nanosleep - high resolution sleep

SYNOPSIS
       #include <time.h>

       int nanosleep(const struct timespec *rqtp,
            struct timespec *rmtp);

DESCRIPTION
       The nanosleep() function causes the current thread to be suspended from
       execution until either the time interval specified by the rqtp argument
       has  elapsed  or  a  signal  is delivered to the calling thread and its
       action is to invoke a signal-catching  function  or  to  terminate  the
       process.  The  suspension time may be longer than requested because the
       argument value is rounded up to an integer multiple of the sleep  reso‐
       lution  or  because  of the scheduling of other activity by the system.
       But, except for the case of being interrupted by a signal, the  suspen‐
       sion time will not be less than the time specified by rqtp, as measured
       by the system clock, CLOCK_REALTIME.


       The use of the nanosleep() function has no  effect  on  the  action  or
       blockage of any signal.

RETURN VALUES
       If  the  nanosleep()  function  returns  because the requested time has
       elapsed, its return value is 0.


       If the nanosleep() function returns because it has been interrupted  by
       a signal, the function returns a value of −1 and sets errno to indicate
       the interruption. If the rmtp argument is non-NULL, the timespec struc‐
       ture  referenced by it is updated to contain the amount of time remain‐
       ing in the interval (the requested time minus the time actually slept).
       If the rmtp argument is NULL, the remaining time is not returned.


       If  nanosleep()  fails,  it  returns  −1 and sets errno to indicate the
       error.

ERRORS
       The nanosleep() function will fail if:

       EINTR     The nanosleep() function was interrupted by a signal.


       EINVAL    The rqtp argument specified a nanosecond value less than zero
                 or greater than or equal to 1000 million.


       ENOSYS    The nanosleep() function is not supported by this implementa‐
                 tion.
