Смонтировать файловую систему

Прототип:

#include <sys/mount.h>
int mount( const char *spec,
const char *dir,
int flags,
const char *type,
const void *data,
int datalen );

Аргументы:

spec
A null-terminated string describing a special device (e.g. /dev/hd0t77), or NULL if there's no special device.
dir
A null-terminated string that names the directory that you want to mount (e.g. /mnt/home).
flags
Flags that are passed to the driver:
_MFLAG_OCB
ignore the special device string, and contact all servers.
_MOUNT_READONLY
mark the filesystem mountpoint as read-only.
_MOUNT_NOEXEC
don't allow executables to load.
_MOUNT_NOSUID
don't honor setuid bits on the filesystem.
_MOUNT_NOCREAT
don't allow file creation on the filesystem.
_MOUNT_OFF32
limit off_t to 32 bits.
_MOUNT_NOATIME
disable logging of file access times.
_MOUNT_BEFORE
call resmgr_attach() with _RESMGR_FLAG_BEFORE.
_MOUNT_AFTER
call resmgr_attach() with _RESMGR_FLAG_AFTER.
_MOUNT_OPAQUE
call resmgr_attach() with _RESMGR_FLAG_OPAQUE.
_MOUNT_UNMOUNT
unmount this path.
_MOUNT_REMOUNT
this path is already mounted; perform an update.
_MOUNT_FORCE
force an unmount or a remount change.
_MOUNT_ENUMERATE
autodetect on this device.
type
A null-terminated string with the filesystem type (e.g. nfs, cifs, qnx4, ext2, network).
data
A pointer to additional data to be sent to the manager. If datalen is <0, the data points to a null-terminated string.
datalen
The length of the data, in bytes, that's being sent to the server, or <0 if the data is a null-terminated string.

Описание:

The mount() function sends a request to servers to mount the services provided by spec and type at dir.

If you set _MFLAG_OCB in the flags, then the special device string is ignored, and all servers are contacted. If you don't set this bit, and the special device spec exists, then only the server that created that device is contacted, and the full path to spec is provided.

If datalen is any value <0, and there's a data pointer, the function assumes that the data pointer is a pointer to a string.
