t_getprotaddr(3)t_getprotaddr(3)NAMEt_getprotaddr() - get the protocol address
SYNOPSISDESCRIPTION
The 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 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 speci‐
fies the length of the address. If the transport endpoint is in the
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 trans‐
port endpoint is not in the state, zero is returned in the len field of
peeraddr.

RETURN VALUE

ERRORS
On failure, is set to the following
[TBADF] The specified identifier 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.
[TSYSERR] A system error has occurred during execution of this
function.
[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 (
