Alternative keyboard hook DLL self-installation hook

#pragma data_seg ()            static HHOOK g_hKeyboardHook = NULL;            static HINSTANCE g_hInst        = NULL;#pragma data_seg ()#pragma comment (linker, "/section:Shared, rws")BOOL WINAPI DllMain(HINSTANCE hInstance, DWORD fdwReason, PVOID pvReserved) {     switch(fdwReason){       case DLL_PROCESS_ATTACH:       g_hInst =      (HINSTANCE) hInstance; 。。。。。

Then use two output functions: one installation hook and the other one uninstallation hook.

MY_API BOOL HookKey (){       ....       g_hKeyboardHook     = ::SetWindowsHookEx(WH_KEYBOARD, KeyboardProc,     g_hInst,     NULL);       ....}

CreateRemoteThread: Call the export function of the installation hook.
