NAME

6       explain_mount_or_die - mount file system and report errors
7

SYNOPSIS

9       #include <libexplain/mount.h>
10       void explain_mount_or_die(const char *source, const char *target, const
11       char *file_systems_type, unsigned long flags, const void *data);
12       int explain_mount_on_error(const  char  *source,  const  char  *target,
13       const char *file_systems_type, unsigned long flags, const void *data);

DESCRIPTION

16       The  explain_mount_or_die  function is used to call the mount(2) system
17       call. On failure an explanation will be  printed  to  stderr,  obtained
18       from  the explain_mount(3) function, and then the process terminates by
19       calling exit(EXIT_FAILURE).
20
21       The explain_mount_on_error function is used to call the mount(2) system
22       call.  On  failure  an  explanation will be printed to stderr, obtained
23       from the explain_mount(3) function, but still returns to the caller.
24
25       source  The source, exactly as to be  passed  to  the  mount(2)  system
26               call.
27
28       target  The  target,  exactly  as  to  be passed to the mount(2) system
29               call.
30
31       file_systems_type
32               The file_systems_type, exactly as to be passed to the  mount(2)
33               system call.
34
35       flags   The flags, exactly as to be passed to the mount(2) system call.
36
37       data    The data, exactly as to be passed to the mount(2) system call.

RETURN VALUE

40       The explain_mount_or_die function only returns on success, see mount(2)
41       for more information. On failure, prints an explanation and  exits,  it
42       does not return.
43
44       The  explain_mount_on_error function always returns the value return by
45       the wrapped mount(2) system call.
46

EXAMPLE

48       The explain_mount_or_die function is intended to be used in  a  fashion
49       similar to the following example:
50              explain_mount_or_die(source, target, file_systems_type, flags, data);
