NAME¶
explain_waitpid_or_die - wait for process to change state and report errors
SYNOPSIS¶
#include <libexplain/waitpid.h>
int pid = explain_waitpid_or_die(int pid, int *status, int options);
DESCRIPTION¶
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);
- pid
- The pid, exactly as to be passed to the waitpid(2)
system call.
- status
- The status, exactly as to be passed to the
waitpid(2) system call.
- options
- The options, exactly as to be passed to the
waitpid(2) system call.
- Returns:
- This function only returns on success. On failure, prints
an explanation and exits.
