本文主要是介绍揭秘gapfnScSendMessage数组大部分都是NtUserMessageCall，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

揭秘gapfnScSendMessage数组大部分都是NtUserMessageCall

第一部分A：

client/clmsg.c里面的

RealDefWindowProcWorker函数里面大量调用了CsSendMessage函数

第一部分B：

client/usercli.h文件里有CsSendMessage函数的宏定义

#define CsSendMessage(hwnd, msg, wParam, lParam, xParam, pfn, bAnsi) \

        (((msg) >= WM_USER) ? \

            NtUserMessageCall(hwnd, msg, wParam, lParam, xParam, pfn, bAnsi) : \

            gapfnScSendMessage[MessageTable[msg].iFunction](hwnd, msg, wParam, lParam, xParam, pfn, bAnsi))

第一部分C：

LRESULT RealDefWindowProcWorker(

    PWND pwnd,

    UINT message,

    WPARAM wParam,

    LPARAM lParam,

    DWORD fAnsi)

{

    HWND hwnd = HWq(pwnd);

    int icolBack;

    int icolFore;

    PWND pwndParent;

    HWND hwndDefIme;

    PWND pwndDefIme;

    PIMEUI pimeui;

#if DBG

    if (!gfTurboDWP) {

        return CsSendMessage(hwnd, message, wParam, lParam, 0L,

                FNID_DEFWINDOWPROC, fAnsi);

    } else {

#endif

    if (FDEFWINDOWMSG(message, DefWindowMsgs)) {

        return CsSendMessage(hwnd, message, wParam, lParam, 0L,

                FNID_DEFWINDOWPROC, fAnsi);
