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) system 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);
