t_close(3N)t_close(3N)NAMEt_close - close a transport endpoint
SYNOPSIS
#ifdef _XOPEN_SOURCE
#include <xti.h>
#else
#include <tiuser.h>
#endif
int t_close(fd)
int fd;
DESCRIPTION
The t_close 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, 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, 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.
This function resides within both the X/Open compliant libxnet and the
SVR4 compliant libnsl Network Services libraries. Network Services
applications which require X/Open compliance must link-load with -lxnet.
Network Services applications which require SVR4 compliance must link-
load with -lnsl.
On failure, t_errno may be set to the following:
[TBADF] The specified file descriptor does not refer to a transport
endpoint.
SEE ALSOt_getstate(3N), t_open(3N), t_unbind(3N)DIAGNOSTICSt_close returns 0 on success and -1 on failure and t_errno is set to
indicate the error.
