C++ CopyFile,MoveFile用法案例详解

#include <fstream>
#include <windows.h>
 
int main()
{
	char *fn = "test.txt";
 
	std::ofstream out(fn);
	if (!out.is_open())
		return 0;
	out.close();
 
	WCHAR buf[256];
	memset(buf, 0, sizeof(buf));
	MultiByteToWideChar(CP_ACP, 0, fn, strlen(fn) + 1, buf, sizeof(buf) / sizeof(buf[0]));
	CopyFile(buf, L"../file/output.txt", FALSE);//FALSE:如果目标位置已经存在同名文件，就覆盖，return 1
												//TRUE:如果目标位置已经存在同名文件，则补拷贝，return 0
												//后者路径若不错在，return 0
	system("pause");
	return 1;
}

	MultiByteToWideChar(CP_ACP, 0, fn, strlen(fn) + 1, buf, sizeof(buf) / sizeof(buf[0]));
	MoveFile(buf, L"../file/output.txt");//FALSE:将前者移动到后者中(后者路径若不错在，return 0)
 
	system("pause");
	return 1;
