getpeername(3c)

Standard C Library Functions                                   getpeername(3C)



NAME
       getpeername - get the name of the peer socket

SYNOPSIS
       #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.


       The caller is responsible for providing a pointer to a memory buffer of
       suitable  size  in  the  address  argument  (typically  a  struct sock‐
       addr_storage), and providing the size  of  that  buffer  in  the  value
       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  com‐
                  plete the call.


       ENOSR      There  were insufficient STREAMS resources available for the
                  operation to complete.
