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.
