 T_GETPROTADDR 3NSL "May 7, 1998"
 NAME
t_getprotaddr - get the protocol addresses
 SYNOPSIS

#include <xti.h>

int t_getprotaddr(int fd, struct t_bind *boundaddr,
 struct t_bind *peeraddr);


 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_getprotaddr() function returns local and remote protocol addresses
currently associated with the transport endpoint specified by fd. In
boundaddr and peeraddr the user specifies maxlen, which is
the maximum size (in bytes) of the address buffer, and buf which points
to the buffer where the address is to be placed. On return, the buf field
of boundaddr points to the address, if any, currently bound to fd,
and the len field specifies the length of the address. If the transport
endpoint is in the T_UNBND state, zero is returned in the len field
of boundaddr. The buf field of peeraddr points to the
address, if any, currently connected to fd, and the len field
specifies the length of the address. If the transport endpoint is not in the
T_DATAXFER, T_INREL, T_OUTCON or T_OUTREL states, zero
is returned in the len field of peeraddr. If the maxlen
field of boundaddr or peeraddr is set to zero, no address is
returned.
 RETURN VALUES

Upon successful completion, a value of 0 is returned. Otherwise, a
value of -1 is returned and t_errno is set to indicate the error.
 VALID STATES

ALL - apart from T_UNINIT.
 ERRORS

On failure, t_errno is set to one of the following:
TBADF

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


TBUFOVFLW

The number of bytes allocated for an incoming argument (maxlen) is
greater than 0 but not sufficient to store the value of that argument.


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).


TSYSERR

A system error has occurred during execution of this function.


 TLI COMPATIBILITY

In the TLI interface definition, no counterpart of this routine was
defined.
