NAME
explain_wait4_or_die - wait for process to change state and report
errors
SYNOPSIS
#include <libexplain/wait4.h>
void explain_wait4_or_die(int pid, int *status, int options, struct
rusage *rusage);
DESCRIPTION
The explain_wait4_or_die function is used to call the wait4(2) system
call. On failure an explanation will be printed to stderr, obtained
from explain_wait4(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:
explain_wait4_or_die(pid, status, options, rusage);
pid The pid, exactly as to be passed to the wait4(2) system call.
status The status, exactly as to be passed to the wait4(2) system
call.
options The options, exactly as to be passed to the wait4(2) system
call.
rusage The rusage, exactly as to be passed to the wait4(2) system
call.
Returns:
This function only returns on success, see wait4(2) for more
information. On failure, prints an explanation and exits.
