explain_usleep_or_die(3)   Library Functions Manual   explain_usleep_or_die(3)

NAME
       explain_usleep_or_die  -	 suspend execution for ms intervals and	report
       errors

SYNOPSIS
       #include	<libexplain/usleep.h>
       void explain_usleep_or_die(long long usec);
       int explain_usleep_on_error(long	long usec);

DESCRIPTION
       The explain_usleep_or_die function is used to call the usleep(3)	system
       call.  On  failure  an  explanation will	be printed to stderr, obtained
       from the	explain_usleep(3) function, and	then the process terminates by
       calling exit(EXIT_FAILURE).

       The explain_usleep_on_error function is used to call the	usleep(3) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from the	explain_usleep(3) function, but	still returns to the caller.

       usec    The usec, exactly as to be passed to the	usleep(3) system call.

RETURN VALUE
       The   explain_usleep_or_die  function  only  returns  on	 success,  see
       usleep(3) for more information. On failure, prints an  explanation  and
       exits, it does not return.

       The explain_usleep_on_error function always returns the value return by
       the wrapped usleep(3) system call.

EXAMPLE
       The explain_usleep_or_die function is intended to be used in a  fashion
       similar to the following	example:
	      explain_usleep_or_die(usec);
