VS2013遍历目录下所有文件时产生中断错误

void getFiles(char* path, vector<string>& files)
{
	string p = path;
	size_t f = p.find("*");
	string p1 = p.substr(0, f);


	long handle;    

	struct _finddata_t fileinfo;
	handle = _findfirst(path, &fileinfo);
	if (-1 == handle)return;

	files.push_back(p1.append(fileinfo.name));

	while (!_findnext(handle, &fileinfo))
	{
		files.push_back(p1.append(fileinfo.name));
	}

	_findclose(handle);
}

原因：_findfirst()返回类型是intptr_t而不是long，从intptr_t转换为long的过程中丢失了数据。

解决：将handle的类型修改为intptr_t即可。

void getFiles(char* path, vector<string>& files)
{
	string p = path;
	size_t f = p.find("*");
	string p1 = p.substr(0, f);


	//long handle;
	intptr_t handle = 0;

	struct _finddata_t fileinfo;
	handle = _findfirst(path, &fileinfo);
	if (-1 == handle)return;

	files.push_back(p1.append(fileinfo.name));

	while (!_findnext(handle, &fileinfo))
	{
		files.push_back(p1.append(fileinfo.name));
	}

	_findclose(handle);
}
