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);
