VC ++的std :: atoll [英] std::atoll with VC++

问题描述

我一直在使用cstdlib中的std::atoll将带有gcc的字符串转换为int64_t. Windows工具链上似乎没有该功能(使用Visual Studio Express 2010).最好的选择是什么?

I have been using std::atoll from cstdlib to convert a string to an int64_t with gcc. That function does not seem to be available on the Windows toolchain (using Visual Studio Express 2010). What is the best alternative?

我也有兴趣将strings转换为uint64_t.取自cstdint的整数定义.

I am also interested in converting strings to uint64_t. Integer definitions taken from cstdint.
