I just gave the latter a look-see.
All the functions use Uchar* for their strings, which are all
"typedef u_int16_t Uchar;", and not chars.
Also, wow, I haven't seen the old 'one function per file' thing
in a long time. I'm tempted to cat(1) them all together ;)
But yes, they do have things like strcasecmp() et al. which
seems efficient enough (reformatted a bit):
int uni_strcasecmp(Uchar *s1, Uchar *s2) {
while (1) {
if (uni_tolower(*s1) != uni_tolower(*s2)) {
return uni_tolower(*s1) - uni_tolower(*s2);
}
if (!*s1) return 0;
}
return 0;
}
At first I thought the missing test for !*s2 might be a bug
(eg. if s2 was shorter than s1), but thinking about it, the
if() would get triggered first.
Anyway, that might be a better way to do it; walk the string
doing single char compares with the single char function.
