explain_waitpid_or_die - wait for process to change state and report errors
int pid = explain_waitpid_or_die(int pid, int *status, int options);
The explain_waitpid_or_die function is used to call the waitpid(2) system call. On failure an explanation will be printed to stderr, obtained from explain_waitpid(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_waitpid_or_die(pid, status, options);
- The pid, exactly as to be passed to the waitpid(2) system call.
- The status, exactly as to be passed to the waitpid(2) system call.
- The options, exactly as to be passed to the waitpid(2) system call.
- This function only returns on success. On failure, prints an explanation and exits.
