Write function:
#include<stdlib.h>

    int StringToInt(char *str)
      {
          char c;
         
          int i,digit=0;
          int k=1;
 
          for(i=strlen(str);i>0;i--)
            {
              digit+=(str-'0')*k;
              k*=10;
            };
         
        return digit;  
     }

This function convert String to unsigned Integer.  WARNING this function not check input argument

There is a C function (on POSIX-systems, which anope is designed for) which converts strings to integers: http://www.die.net/doc/linux/man/man3/strtol.3.html
