t_getprotaddr(3N)
NAME
t_getprotaddr − get the protocol addresses
SYNOPSIS
cc [ flag ... ] file ... −lnsl [ library ... ]
#include <xti.h>
int t_getprotaddr(int fd, struct t_bind ∗boundaddr, struct t_bind ∗peeraddr);
DESCRIPTION
t_getprotaddr() returns local and remote protocol addresses currently associated with the transport endpoint specified by fd.
(maxlen and other members of netbuf are described in t_connect(3N).) 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 state, zero is returned in the len field of peeraddr. If the maxlen field of boundaddr or peeraddr was set to zero, no address is returned.
VALID STATES
Legitimate states (see t_getstate(3N)) for a call to this routine are every one except T_UNINIT .
RETURN VALUES
t_getprotaddr() returns:
0 On success.
−1 On failure.
On failure, t_errno is set to indicate the error, and possibly errno is set.
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.
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 t_errno value.
TLI COMPATIBILITY
In the TLI interface definition, no counterpart of this routine was defined.
