       long strtol( const char *str, char **endptr, int base )
       unsigned long strtoul( const char *s, char **endptr, int radix )

       - prototype in string.h

       - converts string str to long (or unsigned long) value
       - stops reading at first character that cannot be interpreted
         as part of a long value, returning in *endptr
       - str must have format:


         where [ws]  = optional whitespace
               [sn]  = optional sign (+-)
               [0]   = optional zero
               [x]   = optional x or X
               [ddd] = optional digits

        - base is between 2 and 36; if 0, first few characters of str
          determines base to be used (oct,hex or dec) any other value
          of base is illegal
