mount (ULTRIX) mount (ULTRIX)
NAME
mount, umount - Mounts and dismounts file systems
DIFFERENCES
Digital UNIX provides two versions of mount() and unmount(), one for
BSD which is the default, and the other for System V for compatibility.
The BSD version requires sys/mount.h, and the System V version requires
sys/types.h and sys/mount.h. Arguments and type declarations of the two
versions are different. The Digital UNIX version supports NFS, UFS, and
CDFS, but not RFS.
SYSTEM V COMPATIBILITY
Digital UNIX provides the libsys5.a library to allow you to use library
functions that are compatible with System V library functions. This
library contains functions for those libc functions whose behavior is
incompatible with POSIX or X/Open standards. For more information about
the System V (SVID-2) features in Digital UNIX, please refer to the
System V Compatibility User's Guide.
The mount() function does not support specifying the type of file sys‐
tem, mount flags, such as M_RDONLY and M_NOEXEC, or mount data. Allows
you to specify whether the file system is a read-only or read/write
system. Also provides SVID-2 compatibility via the MS_DATA flag.
The umount() function does not support the MNT_NOFORCE, MNT_WAIT,
MNT_FORCE, or MNT_NOWAIT flags.
