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 appropri-
     ate 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 ini-
     tialized 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 direc-
                  tory.

     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.
