NAME

explain_mount_or_die - mount file system and report errors

SYNOPSIS

#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);

DESCRIPTION

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.

EXAMPLE

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);
