  22. I assume you mean convert a character string containing hex digits
  23. ('A'-'F','0'-'9') into a decimal integer. If so, use
  24.  
  25.    unsigned int int_value;
  26.    unsigned long int long_int_value;
  27.    char *string_buffer;
  28.  
  29.    ...
  30.  
  31.    sscanf( string_buffer, "%x", int_value );
  32.  
  33.    sscanf( string_buffer, "%lx", long_int_value );
