void explain_wait3_or_die(int *status, int options, struct rusage *rusage);
DESCRIPTION
The explain_wait3_or_die function
is used to call the wait3(2) system
call. On failure an explanation will be
printed to stderr,
obtained from explain_wait3(3),
and then the process terminates
by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion
similar to the following example:
int pid = explain_wait3_or_die(status, options, rusage);
status
The status, exactly as to be passed to the wait3(2) system call.
options
The options, exactly as to be passed to the wait3(2) system call.
rusage
The rusage, exactly as to be passed to the wait3(2) system call.
Returns:
This function only returns on success.
On failure, prints an explanation and exits.
