For example: FF = 255
              F = 15
              E = 14
              D = 13
              C = 12
              B = 11
              A = 10
              9 = 9
              8 = 8
              7 = 7
              6 = 6
              5 = 5
              4 = 4
              3 = 3
              2 = 2
              1 = 1
              0 = 0

The easy way:

int nInt;
sscanf(pstrYourString, "%x", &nInt);

Or, use 'strtol()':

#include <stdlib.h>

char* pcHex ="0xff";
char* pcCnvEnd;
int   n;

  n = (int) strtol ( pszHex, &pcCnvEnd, 16); // <-- numeric base!!
