Windows編程之文件操作

該程序主要功能就是創(chuàng)建一個文件，然后在文件的后面追加數(shù)據(jù)，之后將文件復(fù)制到上層目錄，然后將其重命名，最后再刪除。
所應(yīng)用到的windows函數(shù)有CreateFile, WriteFile, CopyFile, MoveFile, DeleteFile, SetFilePointer

代碼

#include <windows.h>
#include <stdio.h>


int main(int argc, char* argv[]) {
    HANDLE hFile = CreateFile(argv[1], GENERIC_WRITE, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
    if (hFile == INVALID_HANDLE_VALUE) {
        printf("Create failed\n");
        return 0;
    }
    if (SetFilePointer(hFile, 0, NULL, FILE_END) == -1) {
        printf("SetFilePointer error\n");
        return 0;
    }
    char buff[] = "配置信息";
    DWORD dwWrite;
    if (!WriteFile(hFile, &buff, strlen(buff), &dwWrite, NULL)) {
        printf("Writer error\n");
        return 0;
    }
    printf("往%s寫入數(shù)據(jù)成功\n", argv[1]);
    char newCopyPath[] = "../2.txt";
    char newMovePath[] = "../3.txt";
    if (!CopyFile(argv[1], newCopyPath, FALSE)) {
        printf("CopyFile error\n");
        return 0;
    }
    if (!MoveFile(newCopyPath, newMovePath)) {
        printf("MoveFile error\n");
        return 0;
    }
    if (!DeleteFile(newMovePath)) {
        printf("DeleteFile error\n");
        return 0;
    }
    CloseHandle(hFile);
    return 0;
}
