NAME
explain_wait3_or_die - wait for process to change state and report
errors
SYNOPSIS
#include <libexplain/wait3.h>
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.
