Hex to unsigned char?

george_mercury · 11-27-2004, 01:06 PM

Hi guys!
I need to convert a hexadecimal value (two digit long) from a string and convert it to the coresponding binary value (unsigned char). Is there such a function for that, or do I have to write my own? By the way, I'm programming in C.

Best regards
George

Code:

main()
{
  char *hex="f7";
  int d;
  unsigned char c;
  sscanf(hex,"%02x", &d);
  c=(unsigned char)d;
  printf("%s %02x\n", hex, c);
}
