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.
