getpeername - get name of connected peer SYNOPSIS
cc [ flag ... ] file ... -lsocket -lnsl [ library ... ] #include <sys/types.h> #include <sys/socket.h> 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 trun- cation. 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. ERRORS
The call succeeds unless: EBADF The argument s is not a valid descriptor. ENOMEM There was insufficient user memory for the operation to complete. ENOSR There were insufficient STREAMS resources available for the operation to complete. ENOTCONN The socket is not connected. ENOTSOCK The argument s is not a socket. ATTRIBUTES

getpeername - get the name of the peer socket SYNOPSIS
cc [ flag ... ] file ... -lxnet [ library ... ] #include <sys/socket.h> int getpeername(int socket, struct sockaddr *restrict address, socklen_t *restrict address_len); DESCRIPTION
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. RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
The getpeername() function will fail if: EBADF The socket argument is not a valid file descriptor. EFAULT The address or address_len parameter can not be accessed or written. EINVAL The socket has been shut down. ENOTCONN The socket is not connected or otherwise has not had the peer prespecified. ENOTSOCK The socket argument does not refer to a socket. EOPNOTSUPP The operation is not supported for the socket protocol. The getpeername() function may fail if: ENOBUFS Insufficient resources were available in the system to complete the call. ENOSR There were insufficient STREAMS resources available for the operation to complete. ATTRIBUTES
