C++如何勾住createfile的demo

以下是一个使用C++调用CreateFile函数的示例代码：

#include <windows.h>
#include <iostream>

int main() {
    HANDLE hFile;
    LPCSTR lpFileName = "test.txt";
    DWORD dwDesiredAccess = GENERIC_READ | GENERIC_WRITE;
    DWORD dwShareMode = 0;
    LPSECURITY_ATTRIBUTES lpSecurityAttributes = NULL;
    DWORD dwCreationDisposition = CREATE_ALWAYS;
    DWORD dwFlagsAndAttributes = FILE_ATTRIBUTE_NORMAL;
    HANDLE hTemplateFile = NULL;

    hFile = CreateFile(lpFileName, dwDesiredAccess, dwShareMode, lpSecurityAttributes, dwCreationDisposition, dwFlagsAndAttributes, hTemplateFile);

    if (hFile == INVALID_HANDLE_VALUE) {
        std::cout << "Failed to create file" << std::endl;
        return 1;
    }

    std::cout << "File created successfully" << std::endl;

    CloseHandle(hFile);

    return 0;
}

这个程序创建了一个名为“test.txt”的文件，并且在控制台输出“File created successfully”表示文件创建成功。你可以根据自己的需要修改文件名、访问权限和其他参数。
