Microsoft Detours Pro v3.0

I have only used to Detours 1.5 before, and the documentation for 3.0 isn't great. So in case anyone struggles:

PHP Code:

PVOID SetDetour( PVOID* ppTarget, PVOID pHandler )
{
    if ( DetourTransactionBegin( ) != NO_ERROR )
        return FALSE;

    if ( DetourUpdateThread( GetCurrentThread( ) ) != NO_ERROR )
    {
        DetourTransactionCommit( );
        return NULL;
    }

    PDETOUR_TRAMPOLINE pTrampoline = NULL;
    
    if ( DetourAttachEx( ppTarget, pHandler, &pTrampoline, NULL, NULL ) != NO_ERROR )
    {
        DetourTransactionCommit( );
        return NULL;        
    }

    if ( DetourTransactionCommit( ) != NO_ERROR )
    {
        DetourTransactionAbort( );
        return NULL;
    }

    return pTrampoline;
} 


Retouring works the same, call DetourDetach as opposed to DetourAttach/DetourAttachEx

PHP Code:

    g_lpDispatchMessage = reinterpret_cast<PVOID*>( 0x14317DCD0 );
    oDispatchMessage = reinterpret_cast<tDispatchMessage>( SetDetour( &g_lpDispatchMessage, hkDispatchMessage ) );

    RemoveDetour( &g_lpDispatchMessage, hkDispatchMessage );
