NAME

       explain_nanosleep_or_die - high‐resolution sleep and report errors

SYNOPSIS

       #include <libexplain/nanosleep.h>
       void explain_nanosleep_or_die(const struct timespec *req, struct timespec *rem);
       int explain_nanosleep_on_error(const struct timespec *req, struct timespec *rem);

DESCRIPTION

       The  explain_nanosleep_or_die  function  is  used  to  call  the  nanosleep(2) system call. On failure an
       explanation will be printed to stderr, obtained from the  explain_nanosleep(3)  function,  and  then  the
       process terminates by calling exit(EXIT_FAILURE).

       The  explain_nanosleep_on_error  function  is  used  to  call the nanosleep(2) system call. On failure an
       explanation will be printed to stderr, obtained from the explain_nanosleep(3) function, but still returns
       to the caller.

       req     The req, exactly as to be passed to the nanosleep(2) system call.

       rem     The rem, exactly as to be passed to the nanosleep(2) system call.

RETURN VALUE

       The  explain_nanosleep_or_die function only returns on success, see nanosleep(2) for more information. On
       failure, prints an explanation and exits, it does not return.

       The explain_nanosleep_on_error function always returns the  value  return  by  the  wrapped  nanosleep(2)
       system call.

EXAMPLE

       The  explain_nanosleep_or_die  function  is  intended  to  be  used in a fashion similar to the following
       example:
              explain_nanosleep_or_die(req, rem);
