explain_shmat_or_die
explain_shmat_or_die(3) Library Functions Manual explain_shmat_or_die(3)NAME
explain_shmat_or_die - shared memory attach and report errors
SYNOPSIS
#include <libexplain/shmat.h>
void *explain_shmat_or_die(int shmid, const void *shmaddr, int shmflg);
void *explain_shmat_on_error(int shmid, const void *shmaddr, int shmflg);
DESCRIPTION
The explain_shmat_or_die function is used to call the shmat(2) system call. On failure an explanation will be printed to stderr, obtained
from the explain_shmat(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_shmat_on_error function is used to call the shmat(2) system call. On failure an explanation will be printed to stderr, obtained
from the explain_shmat(3) function, but still returns to the caller.
shmid The shmid, exactly as to be passed to the shmat(2) system call.
shmaddr The shmaddr, exactly as to be passed to the shmat(2) system call.
shmflg The shmflg, exactly as to be passed to the shmat(2) system call.
RETURN VALUE
The explain_shmat_or_die function only returns on success, see shmat(2) for more information. On failure, prints an explanation and exits,
it does not return.
The explain_shmat_on_error function always returns the value return by the wrapped shmat(2) system call.
EXAMPLE
The explain_shmat_or_die function is intended to be used in a fashion similar to the following example:
void *result = explain_shmat_or_die(shmid, shmaddr, shmflg);
