Creating ReClass plugins
ReClass now offers you the ability to create new plugins! Thanks to Timboy67678 for refactoring what was started a couple years ago.
With plugins you can override memory operations such as reading memory, and writing memory. You can also override handle operations such as OpenProcess and OpenThread. The plugin API exposes the ReClass main window, the ribbon bar interface, and the debug console, so can also add your own custom buttons, classes, and types if you want.
Here is a quick rundown of the plugin API and it's callbacks and structures.
Plugin info structure to be filled in during initialization which is passed back to ReClass to display in the plugins dialog
typedef struct _RECLASS_PLUGIN_INFO {
wchar_t Name[256]; //!< Name of the plugin
wchar_t Version[256]; //!< Plugin version
wchar_t About[2048]; //!< Small snippet about the plugin
int DialogId; //!< Identifier for the settings dialog
} RECLASS_PLUGIN_INFO, *PRECLASS_PLUGIN_INFO, *LPRECLASS_PLUGIN_INFO;
Plugin initialization callback to fill in the RECLASS_PLUGIN_INFO struct, and initialize any other plugin resources.
BOOL PLUGIN_CC PluginInit( OUT LPRECLASS_PLUGIN_INFO lpRCInfo )
Callback for when the plugin state is changed (enabled or disabled). Plugins disabled and enabled state are dependent on the implementation inside the plugin. All we do is send a state change to plugins for them to disable or enable their functionality.
VOID PLUGIN_CC PluginStateChange( IN BOOL State )
Window Proc for the settings dialog.
INT_PTR PLUGIN_CC PluginSettingsDlg( IN HWND hWnd, IN UINT Msg, IN WPARAM wParam, IN LPARAM lParam )
Register, remove, get or check overrides for the read/write memory operations.
typedef BOOL(PLUGIN_CC *PPLUGIN_READ_MEMORY_OPERATION)(IN LPVOID Address, IN LPVOID Buffer, IN SIZE_T Size, OUT PSIZE_T BytesRead);
typedef BOOL(PLUGIN_CC *PPLUGIN_WRITE_MEMORY_OPERATION)(IN LPVOID Address, IN LPVOID Buffer, IN SIZE_T Size, OUT PSIZE_T BytesWritten);
BOOL PLUGIN_CC ReClassOverrideReadMemoryOperation( IN PPLUGIN_READ_MEMORY_OPERATION ReadMemoryOperation );
BOOL PLUGIN_CC ReClassOverrideWriteMemoryOperation( IN PPLUGIN_WRITE_MEMORY_OPERATION WriteMemoryOperation );
BOOL PLUGIN_CC ReClassOverrideMemoryOperations( IN PPLUGIN_READ_MEMORY_OPERATION ReadMemoryOperation, IN PPLUGIN_WRITE_MEMORY_OPERATION WriteMemoryOperation );
BOOL PLUGIN_CC ReClassRemoveReadMemoryOverride( VOID );
BOOL PLUGIN_CC ReClassRemoveWriteMemoryOverride( VOID );
BOOL PLUGIN_CC ReClassIsReadMemoryOverriden( VOID );
BOOL PLUGIN_CC ReClassIsWriteMemoryOverriden( VOID );
PPLUGIN_READ_MEMORY_OPERATION PLUGIN_CC ReClassGetCurrentReadMemory( VOID );
PPLUGIN_WRITE_MEMORY_OPERATION PLUGIN_CC ReClassGetCurrentWriteMemory( VOID );
Register, remove, get or check overrides for the opening of handles for various process/thread operations.
typedef HANDLE(PLUGIN_CC *PPLUGIN_OPEN_PROCESS_OPERATION)(IN DWORD dwDesiredAccess, IN BOOL bInheritHandle, IN DWORD dwProcessId);
typedef HANDLE(PLUGIN_CC *PPLUGIN_OPEN_THREAD_OPERATION)(IN DWORD dwDesiredAccess, IN BOOL bInheritHandle, IN DWORD dwThreadId);
BOOL PLUGIN_CC ReClassOverrideOpenProcessOperation( IN PPLUGIN_OPEN_PROCESS_OPERATION OpenProcessOperation );
BOOL PLUGIN_CC ReClassOverrideOpenThreadOperation( IN PPLUGIN_OPEN_THREAD_OPERATION OpenThreadOperation );
BOOL PLUGIN_CC ReClassOverrideHandleOperations( IN PPLUGIN_OPEN_PROCESS_OPERATION OpenProcessOperation, IN PPLUGIN_OPEN_THREAD_OPERATION OpenThreadOperation );
BOOL PLUGIN_CC ReClassRemoveOpenProcessOverride( VOID );
BOOL PLUGIN_CC ReClassRemoveOpenThreadOverride( VOID );
BOOL PLUGIN_CC ReClassIsOpenProcessOverriden( VOID );
BOOL PLUGIN_CC ReClassIsOpenThreadOverriden( VOID );
PPLUGIN_OPEN_PROCESS_OPERATION PLUGIN_CC ReClassGetCurrentOpenProcess( VOID );
PPLUGIN_OPEN_THREAD_OPERATION PLUGIN_CC ReClassGetCurrentOpenThread( VOID );
Print text to the ReClass console window.
VOID CDECL ReClassPrintConsole( IN const wchar_t* Format, ... )
Returns the current attached process handle, null if not attached.
HANDLE PLUGIN_CC ReClassGetProcessHandle( VOID )
Returns the current attached process ID, 0 if not attached.
DWORD PLUGIN_CC ReClassGetProcessId( VOID )
Return the main window handle for ReClass.
HWND PLUGIN_CC ReClassMainWindow( VOID )
Get the ribbon interface for MFC (useful for adding custom buttons and such)
CMFCRibbonBar* PLUGIN_CC ReClassRibbonInterface( VOID )
I have plans to manipulate classes and abstract away the iteration of process modules and memory to plugins so that the plugin API isn't so over complicated and convoluted as it is now.
