EnumDPCallback is an application-defined callback function for the DirectPlayEnumerate function. Depending on whether UNICODE is defined or not, the prototype for the callback function will have lpSPName defined as either the LPWSTR type (for Unicode) or the LPSTR type (for ANSI).
BOOL FAR PASCAL EnumDPCallback( LPGUID lpguidSP, LPSTR/LPWSTR lpSPName, DWORD dwMajorVersion, DWORD dwMinorVersion, LPVOID lpContext );
Returns TRUE to continue the enumeration or FALSE to stop it.
Any pointers returned in a callback function are temporary and are valid only in the body of the callback function. If the application needs to save pointer information, it must allocate memory to hold the data, copy the data, and then store the pointer to this new data. In this function, lpguidSP and lpSPName are temporary.
