string to hex

[archilleswaterland]

hi,
I want to prompt user to enter a hex value and read it as a hex -
this entry will be treated as a memory address
I don't want to bother the user to enter 0x - do I read it as a string
? if yes, how do i convert it to hex ?
thanks,
archilles

You are looking for strtol(), strtoul() called with base 16.

fgets() + strtoul() (base 16)

Bad question. You meant "How do I convert the hex string into a
numerical value ?"
