fdetach(3C)						   Standard C Library Functions 					       fdetach(3C)

NAME
       fdetach - detach a name from a STREAMS-based file descriptor

SYNOPSIS
       #include <stropts.h>

       int fdetach(const char *path);

DESCRIPTION
       The  fdetach()  function  detaches  a STREAMS-based file from the file to which it was attached by a previous call to fattach(3C). The path
       argument points to the pathname of the attached STREAMS file. The process must have appropriate privileges or be the owner of the  file.  A
       successful call to fdetach() causes all pathnames that named the attached STREAMS file to again name the file to which the STREAMS file was
       attached.  All subsequent operations on path will operate on the underlying file and not on the STREAMS file.

       All open file descriptions established while the STREAMS file was attached to the file referenced by path, will still refer to the  STREAMS
       file after the fdetach() has taken effect.

       If  there  are no open file descriptors or other references to the STREAMS file, then a successful call to fdetach() has the same effect as
       performing the last close(2) on the attached file.

RETURN VALUES
       Upon successful completion, fdetach() returns 0. Otherwise, it returns -1 and sets errno to indicate the error.

ERRORS
       The fdetach() function will fail if:

       EACCES	       Search permission is denied on a component of the path prefix.

       EPERM	       The effective user ID is not the owner of path and the process does not have appropriate privileges.

       ENOTDIR	       A component of the path prefix is not a directory.

       ENOENT	       A component of path does not name an existing file or path is an empty string.

       EINVAL	       The path argument names a file that is not currently attached.

       ENAMETOOLONG    The size of a pathname exceeds PATH_MAX, or a pathname component is  longer  than  NAME_MAX  while  _POSIX_NO_TRUNC  is	in
		       effect.

       ELOOP	       Too many symbolic links were encountered in resolving path.

       The fdetach() function may fail if:

       ENAMETOOLONG    Pathname resolution of a symbolic link produced an intermediate result whose length exceeds PATH_MAX.
