getpeername
GETPEERNAME(2) BSD System Calls Manual GETPEERNAME(2)
NAME
getpeername -- get address of connected peer
SYNOPSIS
#include <sys/socket.h>
int
getpeername(int socket, struct sockaddr *restrict address, socklen_t *restrict address_len);
DESCRIPTION
The getpeername() function returns the address of the peer connected to the specified socket.
The address_len parameter should be initialized to indicate the amount of space pointed to by address. On return it contains the actual size
of the address returned (in bytes).
The address is truncated if the buffer provided is too small.
RETURN VALUES
The getpeername() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to
indicate the error.
ERRORS
The call succeeds unless:
[EBADF] The argument socket is not a valid descriptor.
[EFAULT] The address parameter points to memory not in a valid part of the process address space.
[EINVAL] socket has been shut down.
[ENOBUFS] Insufficient resources were available in the system to perform the operation.
[ENOTCONN] Either the socket is not connected or it has not had the peer pre-specified.
[ENOTSOCK] The argument socket refers to something other than a socket (e.g., a file).
[EOPNOTSUPP] getpeername() is not supported for the protocol in use by socket.
SEE ALSO
accept(2), bind(2), getsockname(2), socket(2)
HISTORY
The getpeername() function call appeared in 4.2BSD.
