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

DESCRIPTION

getpeername() returns the name of the peer connected to socket s. The int pointed to by 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), prior to any truncation. The name is truncated if the buffer provided is too small.

RETURN VALUES

If successful, getpeername() returns 0; otherwise it returns −1 and sets errno to indicate the error.
