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);
