T_CLOSE(3N) — NETWORK FUNCTIONS

NAME

t_close − close a transport endpoint

SYNOPSIS

#include <tiuser.h>

int t_close(fd)
int fd;

DESCRIPTION

t_close() 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, t_close() closes the file associated with the transport endpoint.

t_close() should be called from the T_UNBND state (see t_getstate(3N)). However, t_close() 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(2V) 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.

RETURN VALUES

t_close() returns:

0 on success.

−1 on failure and sets t_errno to indicate the error.

ERRORS

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