    itoa() vs. _itoa()

    What's the difference? I have seen itoa() in some places, and other places (like the FAQ, for instance), I see _itoa. Same with atoi() and _atoi().

    The standard form of C name mangling (for the __cdecl ("C Calling Convention") calling convention, which is usually the default, unless you changed your project settings) is simply to prepend an underscore.

    Interoperability between C and C++ means that the names sometimes get a bit messed up, so nobody knows what works and what doesn't. Basically, just use whichever one works - it'll resolve to the same code in the library.
