IFWXNetworkSocket::GetSockOpt method

Applies to: desktop apps only

The GetSockOpt method retrieves a socket option. This method is similar to the Winsock getsockopt function.

Syntax

HRESULT GetSockOpt(
  [in]       int level,
  [in]       int optname,
  [out]      CHAR *optval,
  [in, out]  int optlen
);

Parameters

• level [in]
  Level at which the option is defined. The supported levels include SOL_SOCKET and IPPROTO_TCP.

• optname [in]
  Socket option for which the value is to be retrieved.

• optval [out]
  Pointer to a buffer that receives the value of the requested option.

• optlen [in, out]
  Size, in bytes, of the optval buffer.

Return value

This method returns S_OK if the call is successful; otherwise, it returns an error code.

For an IFWXNetworkSocket interface created by a call to IFWXSession::CreateNetworkSocket, this method returns E_NOTIMPL.
