So the dbLimbName function returns char* of the limb's name obviously. I can compare the name with a string using strcmp(), or return the length using strlen(), or even return the position of a spacific character using strcspn().

What I want to really do is retrieve the character in a specific slot. Like the first letter or the fifth letter.

Have you considered using std::string?
I use it a lot and it's an easy and safe way to handle strings.

You could then do it like this:

You should try this yourself.. it gives a linker error

I think it is because what dbLimbName return's.

maybe I should have this Jaguar eat your brains for your bad advice

Use the subscript operator: []

I don't see how I am sapposed to extract from dbLimbName the characters to place in the array char str[32];

[edit] Ok I got it, sorry for being pissy btw.

As _Pauli_ says, use std::string, it gives you bounds checking when using the [] operator. However, make sure you store the returned string in a char* first, then copy it into the std::string and finally delete[] the char* string, else you'll leak memory.

As for the linker errors, there's a billion threads around here about this and describing the solution.

I guess that's supposed to be a joke. A simple "Thank you" would have been enough.
Set your runtime to /MT (instead of /MTd) in your project settings or build in Release mode and you shouldn't have linker errors with <string> anymore.
Man, use it. It will solve all your string related problems forever.
