NAME

6       explain_shmat_or_die - shared memory attach and report errors

SYNOPSIS

9       #include <libexplain/shmat.h>
10       void *explain_shmat_or_die(int shmid, const void *shmaddr, int shmflg);
11       void  *explain_shmat_on_error(int  shmid, const void *shmaddr, int shm‐
12       flg);

DESCRIPTION

15       The explain_shmat_or_die function is used to call the  shmat(2)  system
16       call.  On  failure  an  explanation will be printed to stderr, obtained
17       from the explain_shmat(3) function, and then the process terminates  by
18       calling exit(EXIT_FAILURE).
19
20       The explain_shmat_on_error function is used to call the shmat(2) system
21       call. On failure an explanation will be  printed  to  stderr,  obtained
22       from the explain_shmat(3) function, but still returns to the caller.
23
24       shmid   The shmid, exactly as to be passed to the shmat(2) system call.
25
26       shmaddr The  shmaddr,  exactly  as  to be passed to the shmat(2) system
27               call.
28
29       shmflg  The shmflg, exactly as to be  passed  to  the  shmat(2)  system
30               call.
31

RETURN VALUE

33       The explain_shmat_or_die function only returns on success, see shmat(2)
34       for more information. On failure, prints an explanation and  exits,  it
35       does not return.
36
37       The  explain_shmat_on_error function always returns the value return by
38       the wrapped shmat(2) system call.
39

EXAMPLE

41       The explain_shmat_or_die function is intended to be used in  a  fashion
42       similar to the following example:
43              void *result = explain_shmat_or_die(shmid, shmaddr, shmflg);
