    It turns a string to lower case? edit: that is, it copies a string to s as lower case (but I'm still not actually sure)

      Well, you're right, but why would anyone want to do a bitwise XOR on a character in a string. Is this some sort of half-assed encryption thing, or maybe converting a string from Base64 characters to ascii?

          Removes sql injection?

            Why that's obvious. It makes you hate the coder who spewed it into your source.

            Yeah, that was me. Only for the sake of being cryptic though, although I'm starting to think we need more code like that these days. Beats 'design patterns'.

                  But it only xors with 0x20 if it's already upper case (or a non-ascii char between 0xC0 and 0xDF) Undeserved 2-vote.

                            increment the address of s set the value of s to the value of t and increment t. the value of t is dependent on the if statement. AND the value of t with 0x60 and if bit 6 is set, make the value of s = the value of t exclusive ored with 32,otherwise set s to the value of t... then increment the address of t. do this until the value of s is not true.

                                    It definitely returns a string with all lowercase characters.

                                          Yeah, converts to lower case is right - but don't forget it also does '@' => '`', '[' => '{', '\' => '|', ']' => '}', '^' => '-', and '_' => del. Just felt the need to punctuate it. :)
