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.
