NANOSLEEP(2)		   BSD Programmer's Manual		  NANOSLEEP(2)

NAME
     nanosleep - high resolution sleep

SYNOPSIS
     #include <time.h>

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

DESCRIPTION
     nanosleep() suspends execution of the calling process for the time speci-
     fied. An unmasked signal will cause it to terminate the sleep early, re-
     gardless of the SA_RESTART value on the interrupting signal.

RETURN VALUES
     If the nanosleep() function returns because the requested time has
     elapsed, the value returned will be zero.

     If the nanosleep() function returns due to the delivery of a signal, the
     value returned will be -1, and the global variable errno will be set to
     indicate the interruption. If rmtp is non-null, the timespec structure it
     references is updated to contain the unslept amount (the request time
     minus the time actually slept).

ERRORS
     If any of the following conditions occur, the nanosleep() function shall
     return -1 and set errno to the corresponding value.

     [EFAULT]	   Either rqtp or rmtp points to memory that is not a valid
		   part of the process address space.

     [EINTR]	   nanosleep was interrupted by the delivery of a signal.

     [EINVAL]	   rqtp specified a nanosecond value less than zero or greater
		   than 1000 million, or a second value less than zero or
		   greater than 100 million.

     [ENOSYS]	   nanosleep is not supported by this implementation.

SEE ALSO
     sleep(3)

STANDARDS
     The nanosleep() function conforms to IEEE Std 1003.1b-1993 ("POSIX").
