Hex conversion

I need to convert string "A1A2A3A4" to "\xA1\xA2\xA3\xA4"
and "\xA1\xA2\xA3\xA4" to "A1A2A3A4".

I can do this by splitting string "A1A2A3A4" on "A1" "A2" "A3" "A4"
and then passing to strtol("0xA1", &stopstring, 16);
The result added to string. Is it possible to do this using sscanf and sprintf.


Thank you for any better idea.

What exactly do you mean by "\xA1 ....."
Are you trying to convert from one base to another?

Yes. I've done this. But I believe that there is a simplier decision with sscanf and sprintf functions using.

Have you used them for this purpose?
