This should be setting lpRemoteLibraryBuffer with the return value from VirtualAllocEx?

if( !lpRemoteLibraryBuffer )
break;

// write the image into the host process...
if( !WriteProcessMemory( hProcess, lpRemoteLibraryBuffer, lpBuffer, dwLength, NULL ) )
break;


// change the permissions to (RX) to bypass W^X protections
if (!VirtualProtectEx(hProcess, lpRemoteLibraryBuffer, dwLength, PAGE_EXECUTE_READ, NULL))
break;

// add the offset to ReflectiveLoader() to the remote library address...
lpReflectiveLoader = (LPTHREAD_START_ROUTINE)( (ULONG_PTR)lpRemoteLibraryBuffer + dwReflectiveLoaderOffset );
