HRESULT BuildAddress(
const WCHAR *const wszAddress,
const USHORT usPort
);

Parameters

wszAddress

[in] Remote host address can be a dotted Internet address—for example, 127.0.0.1—or a valid host name—for example, example.microsoft.com.

usPort

[in] Port on the remote host to which to connect.

Return Values

Returns S_OK if successful, or one of the following error values.

Remarks

Note  The DPNSVR is a DirectPlay feature that allows multiple processes to share a single port for enumeration. Do not use the DPNA_DPNSVR_PORT flag when constructing a device address, or when making a connection. This flag should only be used for enumerations. If you do not add a port element to the enumeration address, the port represented by the flag will be automatically added to that address. See Using the DirectPlay DPNSVR Application for a further discussion of DPNSVR.
