X/Open Networking Services Library Functionsgetpeername(3XNET)


NAME

 getpeername - get the name of the peer socket

SYNOPSIS

 
cc [ flag ... ] file ... -lxnet [ library ... ]
#include <sys/socket.h>
 
int getpeername(int socket, struct sockaddr *address, socklen_t *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.
