NAME

       fattach() - attach a STREAMS file descriptor to an object in the file system name space

SYNOPSIS

DESCRIPTION

       The  function  attaches	the  fd  file descriptor to an object in the file system name space designated by path.  fd specifies an open file
       descriptor to a STREAMS device or STREAMS-based pipe.  path specifies the pathname of an existing object in the	file  system.	A  STREAMS
       device  or pipe can be attached to more than one node in the file system name space. In other words, a STREAMS device or pipe is allowed to
       have several associated names.  Until the STREAMS device or pipe is detached from the node (with fdetach(3C) or	fdetach(1M)),  all  opera-
       tions on path will act on the STREAMS device or pipe instead of the file system object path.

       The stream's attributes (see the stat(2) reference page) are set according to the following scheme:

       o  The group ID, user ID, times, and permissions are set to those of path.

       o  The size as well as the device number are set to those of the STREAMS device or pipe designated by the fd parameter.	Note that although
	  the attributes of the STREAMS device or pipe may change (see the chmod(2) reference page), the attributes of the underlying file  system
	  object path will not be changed.

       o  The number of links is set to 1.

RETURN VALUE

       Upon  successful  completion,  the  function  returns  a value of 0 (zero). Otherwise, it returns a value of -1, and is set to indicate the
       error.

ERRORS

       If any of the following conditions occurs, the function sets to the value that corresponds to the condition.

       [EACCES] 	     Although the user is the owner of path, the user has no write permissions for it.

       [EBADF]		     The fd parameter is an invalid file descriptor.

       [EBUSY]		     The existing object specified by the path parameter is already mounted or has a file descriptor attached to it.

       [EFAULT] 	     The path parameter points to a location outside of the allocated address space of the process.

       [EINVAL] 	     The fd parameter does not refer to a STREAMS device or STREAMS-based pipe.

       [ELOOP]		     When path was translated, too many symbolic links were found.

       [ENOENT] 	     path does not exist.

       [ENOTDIR]	     The directory portion of the path parameter does not exist.

       [ENAMETOOLONG]	     The size of a pathname component is longer than when is in effect, or the pathname length is longer than

       [EPERM]		     The current effective user ID is not the owner of the existing object specified by the path parameter.

NAME

       fdetach() - detach a name from a STREAMS file descriptor

SYNOPSIS

DESCRIPTION

       The  function  detaches	a  file descriptor from a name in the file system designated by path.  path specifies the path name of an existing
       object in the file system name space that was previously attached (see fattach(3C)).  As a result of the operation, the node's  status  and
       permissions  return  to	the  state prior to the file attaching to the node.  Any later operations on path will affect only the file system
       node and not the attached file.

   Security Restrictions
       The function is restricted to superusers, or users with the privilege, or those who own path and have write  permission.   In  addition	to
       having  the  privilege, or privileges may also be required.  See privileges(5) for more information about privileged access on systems that
       support fine-grained privileges.

RETURN VALUE

       Upon successful completion, the function returns a value of 0 (zero).  Otherwise, it returns a value of -1 is returned, and is set to indi-
       cate the error.

ERRORS

       If any of the following conditions occurs, the function sets to the value that corresponds to the condition.

       The		     path parameter points outside the process' allocated address space.

       The user does not have the correct permission to access the file.
			     See the section.

       The object pointed to by the
			     path parameter is not fattached to a STREAMS device or pipe.

       When		     path was translated, too many symbolic links were found.

       The		     path parameter points to a path name that does not exist.

       The directory portion of the
			     path parameter does not exist.

       The size of a path name component is longer than
			     when is in effect, or the path name length is longer than

       The current effective user ID is not the owner of the existing object
			     specified	by  the  path parameter, or the current effective user ID does not specify a user with the correct permis-
			     sions.
