explain_mount_or_die3
Mount file system and report errors
Usage
#include <libexplain/mount.h>
void explain_mount_or_die(const char *source, const char *target, const char *file_systems_type, unsigned long flags, const void *data);
int explain_mount_on_error(const char *source, const char *target, const char *file_systems_type, unsigned long flags, const void *data);
Overview
The explain_mount_or_die function is used to call the mount(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_mount(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_mount_on_error function is used to call the mount(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_mount(3) function, but still returns to the caller.
source
|
The source, exactly as to be passed to the mount(2) system call. |
|---|---|
target
|
The target, exactly as to be passed to the mount(2) system call. |
file_systems_type
|
The file_systems_type, exactly as to be passed to the mount(2) system call. |
flags
|
The flags, exactly as to be passed to the mount(2) system call. |
data
|
The data, exactly as to be passed to the mount(2) system call. |
Return value
The explain_mount_or_die function only returns on success, see mount(2) for more information. On failure, prints an explanation and exits, it does not return.
The explain_mount_on_error function always returns the value return by the wrapped mount(2) system call.
Examples
The explain_mount_or_die function is intended to be used in a fashion similar to the following example:
explain_mount_or_die(source, target, file_systems_type, flags, data);Releases
