/* This is similar to POSIX strcasecmp except that we don't do the comparison
with unsigned char. We avoid strcasecmp for C standard conformance. */
static int
str_casecmp (const char *s1, const char *s2)
{
size_t i;
for (i = 0;; i++)
{
int c1 = s1[i];
int c2 = s2[i];
if (c1 == 0 || tolower (c1) != tolower (c2))
return c1 - c2;
}
}
Is there a reason not to do the comparison with unsigned char?
In the context of the call, the values will always be nonnegative
so that this is OK, but there is a risk that some future developer
might reuse this function in another context, where it would be
incorrect on platforms with signed char (in particular, there is
no warning in the comment).
