Assuming the hexadecimal number is a string, then you can do it like this:

char buffer[] = "FF";
int value;
sscanf(buffer,"%x", &value);

if its not a string, then let us know what it is.

The hexadecimal number is a combination of characters and numbers. so then how would you convert a number like this 0x0064FDF0 or 1239AS83
Sorry for not responding before now, been away, but:

I presume the data type is a string.

(i.e. it is typed in from the keyboard or read from a file or something like that).  The method above should work in that case.
