Parsing command line arguments in a unicode C++ application

Question

How can I parse integers passed to an application as command line arguments if the app is unicode?

Unicode apps have a main like this:

int _tmain(int         


        

Answer 1

A TCHAR is a character type which works for both ANSI and Unicode. Look in the MSDN documentation (I'm assuming you are on Windows), there are TCHAR equivalents for atoi and all the basic string functions (strcpy, strcmp etc.)

The TCHAR equivalient for atoi() is _ttoi(). So you could write this:

int value = _ttoi(argv[1]);
