t_getstate(3c)
Standard C Library Functions t_getstate(3C)
NAME
t_getstate - get the current state
SYNOPSIS
#include <xti.h>
int t_getstate(int fd);
DESCRIPTION
This routine is part of the XTI interfaces which evolved from the TLI
interfaces. XTI represents the future evolution of these interfaces.
However, TLI interfaces are supported for compatibility. When using a
TLI routine that has the same name as an XTI routine, the tiuser.h
header file must be used. Refer to the TLI COMPATIBILITY section for a
description of differences between the two interfaces.
The t_getstate() function returns the current state of the provider
associated with the transport endpoint specified by fd.
RETURN VALUES
State is returned upon successful completion. Otherwise, a value of -1
is returned and t_errno is set to indicate an error. The current state
is one of the following:
T_UNBND Unbound.
T_IDLE Idle.
T_OUTCON Outgoing connection pending.
T_INCON Incoming connection pending.
T_DATAXFER Data transfer.
T_OUTREL Outgoing direction orderly release sent.
T_INREL Incoming direction orderly release received.
If the provider is undergoing a state transition when t_getstate() is
called, the function will fail.
ERRORS
On failure, t_errno is set to one of the following:
TBADF The specified file descriptor does not refer to a trans‐
port endpoint.
TPROTO This error indicates that a communication problem has
been detected between XTI and the transport provider for
which there is no other suitable XTI error (t_errno).
TSTATECHNG The transport provider is undergoing a transient state
change.
TSYSERR A system error has occurred during execution of this
function.
TLI COMPATIBILITY
The XTI and TLI interface definitions have common names but use differ‐
ent header files. This, and other semantic differences between the two
interfaces are described in the subsections below.
Interface Header
The XTI interfaces use the header file, xti.h. TLI interfaces should
not use this header. They should use the header:
#include <tiuser.h>
Error Description Values
The t_errno value that can be set by the XTI interface and cannot be
set by the TLI interface is:
TPROTO
