explain_mount_or_die - mount file system and report errors
#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);
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.
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.
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);
- mount(2)
- mount file system
- explain_mount(3)
- explain mount(2) errors
- exit(2)
- terminate the calling process
