getpeername - get the name of the peer socket
cc [ flag ... ] file ... -lxnet [ library ... ] #include <sys/socket.h> int getpeername(int socket, struct sockaddr *restrict address,
socklen_t *restrict address_len);
The getpeername() function retrieves the peer address of the specified socket, stores this address in the sockaddr structure pointed to by the address argument, and stores the length of this address in the object pointed to by the address_len argument.
If the actual length of the address is greater than the length of the supplied sockaddr structure, the stored address will be truncated.
If the protocol permits connections by unbound clients, and the peer is not bound, then the value stored in the object pointed to by address is unspecified.
Upon successful completion, 0 is returned. Otherwise, −1 is returned and errno is set to indicate the error.
The getpeername() function will fail if:
