Is there a stoll()/stroll() (string to long long) alternative in Visual Studio 2008

Question

Is there an alternative, either built into windows or apache license compatible, to stoll() for Visual Studio 2008. Even installing the windows 7 platform SDK does not add stoll() to the string header.

On unix the same function is be called strtoll().

Answer 1

You can use _strtoi64. It's declared in stdlib.h.

long long num = _strtoi64(str, NULL, 10);

Similarly to strtoll, you can pass a char ** endptr as a second parameter. If so, *endptr will be set to the first invalid character (which may be the normal null-terminator).
