fdetach(3C)                                                     fdetach(3C)


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

   SYNOPSIS
         int fdetach(const char *path);

   DESCRIPTION
         The fdetach routine detaches a STREAMS-based file descriptor from a
         name in the file system.  path is the path name of the object in the
         file system name space, which was previously attached [see
         fattach(3C)]. The user must be the owner of the file or a user with
         the appropriate privileges.  All subsequent operations on path will
         operate on the file system node and not on the STREAMS file.  The
         permissions and status of the node are restored to the state the node
         was in before the STREAMS file was attached to it.

   RETURN VALUE
         If successful, fdetach returns 0; otherwise it returns -1 and sets
         errno to indicate an error.

   ERRORS
         Under the following conditions, the function fdetach fails and sets
         errno to:

         EPERM        The effective user ID is not the owner of path or is not
                      a user with appropriate permissions.

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

         ENOENT       path does not exist.

         EINVAL       path is not attached to a STREAMS file.

         ENAMETOOLONG The size of path exceeds {PATHMAX}, or a path name
                      component is longer than {NAMEMAX} while
                      {POSIXNOTRUNC} is in effect.

         ELOOP        Too many symbolic links were encountered in translating
                      path.
