Message type invalidScanfArgType_in correct?

[antred]

I have a cpp file in which there's a call to sscanf(). The format specifier for the argument is %x, the argument itself is of type std::size_t*.
.
According to http://en.cppreference.com/w/cpp/io/c/fscanf, std::size_t* is a perfectly acceptable argument type for %x, but cppcheck complains:

%x in format string (no. 1) requires 'unsigned int ' but the argument type is 'std::size_t * {aka unsigned long long }'.

Hello!

Sorry for late reply.

According to http://en.cppreference.com/w/cpp/io/c/fscanf, std::size_t* is a perfectly acceptable argument type for %x, but cppcheck complains:

Yes. But as I read it you need the 'z' length modifier.

I am not sure but I think something like:

fscanf(f,"%zx", ..

does that work?
