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.
