t_close(3N)                                                     t_close(3N)

NAME
     tclose - close a transport endpoint

SYNOPSIS
     #include <sys/tiuser.h>

     int tclose(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 associ-
     ated 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.
