getpeername(SSC)


getpeername -- get name of connected peer

Syntax

cc ... -lsocket

int getpeername(s, name, namelen)
int s;
struct sockaddr *name;
int *namelen;

Description

getpeername( ) returns the name of the peer connected to socket s. The namelen parameter should be initialized to indicate the amount of space pointed to by name. On return it contains the actual size of the name returned (in bytes). The interpretation of "name" depends on the "communication domain". (See protocols(SFF) for more information.) Only the Internet domain and the UNIX domain are currently supported.

Return values

A return value of zero indicates that the call succeeded. A return value of -1 indicates that an error occurred, and in this case an error code is stored in the global variable errno.

Diagnostics

The call succeeds unless:

[EBADF]
The s argument is not a valid descriptor.

[ENOTSOCK]
The s argument points to a file, not a socket.

[ENOTCONN]
The socket is not connected.

[ENOBUFS]
Insufficient resources were available in the system to perform the operation.

[EFAULT]
The name parameter points to memory not in a valid part of the process's address space.
