Public bug reported: I wrote this routine to convert a hex string to binary:
https://gist.github.com/Zibri/992b38baa520eb478ef7fa15fd950a7a/raw/2ea3634b31d6c90d74dc2a987a3dfe3b57e6fbcc/hex2bin_by_zibri.c The routine works nicely but I noticed one thing: sscanf("%02x",&char) accepts: 1 02 Aa aA but it also accepts 0x which it translates to 00 There's no real harm in that, but I think that should be corrected. In a loop if the input string (check my routine) is "0x 0x 12 34 0x 1x 12 34" The routine translates 00 00 12 34 00 Because for sscanf 0x is not an error but 1x is. IMHO they should both be treated the same way in "%x"...
