fdetach - detach a name from a STREAMS-based file descriptor
int
fdetach(const char *path);
Unsafe
The fdetach() routine
detaches a STREAMS
-based file descriptor from a name in the file system.
path is the path name of the object in the file system name space, which
was previously attached (see fattach(3C)
). The user must be the owner of
the file or a user with the appropriate privileges. All subsequent operations
on path will operate on the file system node and not on the STREAMS
file.
The permissions and status of the node are restored to the state the node
was in before the STREAMS
file was attached to it.
If successful,
fdetach() returns 0; otherwise it returns -1 and sets errno to indicate
an error.
Under the following conditions, the function fdetach() fails
and sets errno to:
- EINVAL
- path is not attached to a STREAMS
file.
- ELOOP
- Too many symbolic links were encountered in translating path.
- ENAMETOOLONG
- The size of path exceeds {PATH_MAX}, or a path name component is longer
than {NAME_MAX} while {_POSIX_NO_TRUNC} is in effect.
- ENOENT
- path does not
exist.
- ENOTDIR
- A component of the path prefix is not a directory.
- EPERM
- The
effective user ID
is not the owner of path or is not a user with appropriate
permissions.
