NAME
      tclose - close a transport endpoint

SYNOPSIS
      #include <tiuser.h>

      int tclose(fd)
      int fd;

DESCRIPTION
      The tclose function informs the transport provider that the user is
      finished with the transport endpoint specified by fd, and frees any local
      library resources associated with the endpoint.  In addition, tclose
      closes the file associated with the transport endpoint.

      tclose should be called from the TUNBND state [see tgetstate(3N)].
      However, this function does not check state information, so it may be
      called from any state to close a transport endpoint.  If this occurs, the
      local library resources associated with the endpoint will be freed
      automatically.  In addition, close(2) will be issued for that file
      descriptor; the close will be abortive if no other process has that file
      open, and will break any transport connection that may be associated with
      that endpoint.

      On failure, terrno may be set to the following:

      TBADF        The specified file descriptor does not refer to a transport
                   endpoint.

DIAGNOSTICS
      tclose returns 0 on success and -1 on failure and terrno is set to
      indicate the error.
