fdetach(3)
NAME
  fdetach - Detaches a file name from a STREAMS-based file descriptor

LIBRARY
  Standard C Library (libc.so, libc.a)

SYNOPSIS
  #include <stropts.h>
  int fdetach(
	  const char *path);

STANDARDS
  Interfaces documented on this reference page conform to industry standards
  as follows:

  fdetach():  XPG4-UNIX

  Refer to the standards(5) reference page for more information about
  industry standards and associated tags.

PARAMETERS
  path	    Specifies the pathname of an existing object in the file system
	    name space that was previously attached (see the fattach()
	    reference page).

DESCRIPTION
  The fdetach() function separates (detaches) a STREAMS-based file descriptor
  from a name in the file system designated by path.  As a result of this
  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.	The user must either
  have the proper permissions to allow access to the file, or own the file.

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

ERRORS
  If any of the following conditions occurs, the fdetach() function sets
  errno to the value that corresponds to the condition.

  [EACCESS] The user is not the owner of the file or does not have the
	    correct permissions to access the file.

  [EBUSY]   [Digital]  There is an active reference to a file located on the
	    file system.

  [EFAULT]  [Digital]  The path parameter points outside the process's
	    allocated address space.

  [EINVAL]  The object pointed to by the path parameter is not attached to a
	    file.

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

  [ENOENT]  The path parameter points to a pathname that does not exist.

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

  [ENAMETOOLONG]
	    The size of a pathname component is longer than [NAME_MAX] when
	    [_POSIX_NO_TRUNC] is in effect, the pathname length is longer
	    than [PATH_MAX], or the length of the intermediate result of a
	    pathname resolution of a symbolic link is longer than PATH_MAX.

  [EPERM]   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 privileges.

RESTRICTIONS
  [Digital]  The fdetach() function requires that the FFM_FS kernel option be
  configured.  See System Administration for information on configuring
  kernel options.
