fattach(3C)                                                     fattach(3C)


   NAME
         fattach - attach a STREAMS-based file descriptor to an object in the
         file system name space

   SYNOPSIS
         int fattach(int fildes, const char *path);

   DESCRIPTION
         The fattach routine attaches a STREAMS-based file descriptor to an
         object in the file system name space, effectively associating a name
         with fildes.  fildes must be a valid open file descriptor
         representing a STREAMS file.  path 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 file until the STREAMS file is
         detached from the node.  fildes can be attached to more than one
         path, i.e., a stream can have several names associated with it.

         The attributes of the named stream [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 device associated
         with fildes.  If any attributes of the named stream are subsequently
         changed [e.g., chmod(2)], the attributes of the underlying object are
         not affected.

   RETURN VALUE
         If successful, fattach returns 0; otherwise it returns -1 and sets
         errno to indicate an error.

   ERRORS
         Under the following conditions, the function fattach fails and sets
         errno to:

         EACCES       The user is the owner of path but does not have write
                      permissions on path or fildes is locked.

         EBADF        fildes is not a valid open file descriptor.

         ENOENT       path does not exist.

         ENOTDIR      A component of a path prefix is not a directory.

         EINVAL       fildes does not represent a STREAMS file.

         EPERM        The effective user ID is not the owner of path or a user
                      with the appropriate privileges.

         EBUSY        path is currently a mount point or has a STREAMS file
                      descriptor attached it.

         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.

         ELOOP        Too many symbolic links were encountered in translating
                      path.

         EREMOTE      path is a file in a remotely mounted directory.
