Character.forDigit in C++

Character.forDigit((c>>4)&0xF, 16)  

I'm trying to convert some Java code to C++. 95% of the way there but the above Java code has stumped me.

As I understand it, forDigit in Java determines the character representation for a specific digit in the specified radix, in this case.

c in the above code can be anything other than alphanumeric

I've been playing with atol (atol(c.c_str()) >> 4 & 0xF) but this does not give me the desired outcome.

Any pointers would be great!
