The masked edit control's window procedure. Exposed for advanced scenarios; applications do not call it directly.
C
LRESULT CALLBACK SftMask_WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam);
All SftMask/DLL API macros send window messages to the control using SendMessage. If an application is certain that it uses the control from a single (main UI) thread only, it can #define SFTMASK_SINGLETHREADED before including SftMask.h - the API macros then call SftMask_WndProc directly, avoiding the SendMessage overhead.
