获取程序自身窗口句柄（cmd）

大家好，又见面了，我是你们的朋友全栈君。

HWND GetConsoleHwnd(void)
{
#define MY_BUFSIZE 1024 // Buffer size for console window titles.
    HWND hwndFound;         // This is what is returned to the caller.
    char pszNewWindowTitle[MY_BUFSIZE]; // Contains fabricated
    // WindowTitle.
    char pszOldWindowTitle[MY_BUFSIZE]; // Contains original
    // WindowTitle.

    // Fetch current window title.

    GetConsoleTitle(pszOldWindowTitle, MY_BUFSIZE);

    // Format a "unique" NewWindowTitle.

    wsprintf(pszNewWindowTitle, "%d/%d",
        GetTickCount(),
        GetCurrentProcessId());

    // Change current window title.

    SetConsoleTitle(pszNewWindowTitle);

    // Ensure window title has been updated.

    Sleep(40);

    // Look for NewWindowTitle.

    hwndFound = FindWindow(NULL, pszNewWindowTitle);

    // Restore original window title.

    SetConsoleTitle(pszOldWindowTitle);

    return(hwndFound);
}
