NAME
fattach - attach a STREAMS- or doors-based file descriptor to an object
in the file system name space
SYNOPSIS
#include <stropts.h>
int fattach(
int fildes,
const char *path);
DESCRIPTION
The
fattach() function attaches a STREAMS- or doors-based file descriptor
to an object in the file system name space, effectively associating a
name with
fildes. The
fildes argument must be a valid open file
descriptor representing a STREAMS or doors file. The
path argument is a
path name of an existing object and the user must have appropriate
privileges or be the owner of the file and have write permissions. All
subsequent operations on
path will operate on the STREAMS or doors file
until the STREAMS or doors file is detached from the node. The
fildes argument can be attached to more than one
path, that is, a stream or door
can have several names associated with it.
The attributes of the named stream or door (see
stat(2)), are initialized
as follows: the permissions, user ID, group ID, and times are set to
those of
path, the number of links is set to 1, and the size and device
identifier are set to those of the streams or doors device associated
with
fildes. If any attributes of the named stream or door are
subsequently changed (for example,
chmod(2)), the attributes of the
underlying object are not affected.
RETURN VALUES
Upon successful completion,
fattach() returns
0. Otherwise it returns
-1 and sets
errno to indicate an error.
ERRORS
The
fattach() function will fail if:
EACCES The user is the owner of
path but does not have write
permissions on
path or
fildes is locked.
EBADF The
fildes argument is not a valid open file descriptor.
EBUSY The
path argument is currently a mount point or has a
STREAMS or doors file descriptor attached to it.
EINVAL The
path argument is a file in a remotely mounted
directory.
EINVAL The
fildes argument does not represent a STREAMS or doors
file.
ELOOP Too many symbolic links were encountered in translating
path.
ENAMETOOLONG The size of
path exceeds {
PATH_MAX}, or the component of
a path name is longer than {
NAME_MAX} while
{
_POSIX_NO_TRUNC} is in effect.
ENOENT The
path argument does not exist.
ENOTDIR A component of a path prefix is not a directory.
EPERM The effective user ID is not the owner of
path or a user
with the appropriate privileges.
