error C4996: 'std::_Copy_impl'

以下代码段在VS2008编译可以通过，只是会提示不安全；

std::vector<unsigned char> fileData ="asdfsfsfsfsdf";//随便打的
//文件数据大小
int size = fileData.size();
//字节数组
char* data = new char[size + 1];
//把二进制数据复制到数组
std::copy(fileData.begin(), fileData.end(), data);
data[size] = 0;

但在VS2012就不能编译通过,VS2012进行了强制类型检查

1>C:Program FilesMicrosoft Visual Studio 11.0VCincludexutility(2176): error C4996: 'std::_Copy_impl': Function call with parameters that may be unsafe - this call relies on the caller to check that the passed values are correct.

解决：修改代码如下

std::vector<unsigned char> fileData = "sdfasdfasdfasf";
	//文件数据大小
	int size = fileData.size();
	//字节数组
	char* data = new char[size + 1];
	//把二进制数据复制到数组
	std::copy(fileData.begin(), fileData.end(), stdext::unchecked_array_iterator<char*>(data));
	data[size] = 0;
