getsockname(3c)

Standard C Library Functions                                   getsockname(3C)



NAME
       getsockname - get the socket name

SYNOPSIS
       #include <sys/socket.h>

       int getsockname(int socket, struct sockaddr *restrict address,
            socklen_t *restrict address_len);

DESCRIPTION
       The  getsockname()  function  retrieves  the  locally-bound name 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  socket has not been bound to a local name, the value stored in
       the object pointed to by address is unspecified.

RETURN VALUES
       Upon successful completion, 0 is returned, the address argument  points
       to  the  address  of the socket, and the address_len argument points to
       the length of the address. Otherwise, −1 is returned and errno  is  set
       to indicate the error.

ERRORS
       The getsockname() function will fail:

       EBADF         The socket argument is not a valid file descriptor.


       EFAULT        The  address or address_len parameter can not be accessed
                     or written.


       ENOTSOCK      The socket argument does not refer to a socket.


       EOPNOTSUPP    The operation is not supported for this  socket's  proto‐
                     col.



       The getsockname() function may fail if:

       EINVAL     The socket has been shut down.


       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.
