explain_wait3_or_die - wait for process to change state and report errors
#include <libexplain/wait3.h>
void explain_wait3_or_die(int *status, int options, struct rusage *rusage);
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.
- wait3(2)
- wait for process to change state
- explain_wait3(3)
- explain wait3(2) errors
- exit(2)
- terminate the calling process
