NAME¶
explain_kill_or_die - send signal to a process and report errors
SYNOPSIS¶
#include <libexplain/kill.h>
void explain_kill_or_die(pid_t pid, int sig);
int explain_kill_on_error(pid_t pid, int sig);
DESCRIPTION¶
The
explain_kill_or_die function is used to call the
kill(2)
system call. On failure an explanation will be printed to
stderr,
obtained from the
explain_kill(3) function, and then the process
terminates by calling exit(EXIT_FAILURE).
The
explain_kill_on_error function is used to call the
kill(2)
system call. On failure an explanation will be printed to
stderr,
obtained from the
explain_kill(3) function, but still returns to the
caller.
- pid
- The pid, exactly as to be passed to the kill(2)
system call.
- sig
- The sig, exactly as to be passed to the kill(2)
system call.
RETURN VALUE¶
The
explain_kill_or_die function only returns on success, see
kill(2) for more information. On failure, prints an explanation and
exits, it does not return.
The
explain_kill_on_error function always returns the value return by the
wrapped
kill(2) system call.
EXAMPLE¶
The
explain_kill_or_die function is intended to be used in a fashion
similar to the following example:
explain_kill_or_die(pid, sig);
