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.

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 associat-
       ing 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 asso-
       ciated  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.
