As a pure code-movement step, this may be OK, but I am not sure if
both of them want to be public functions in this shape.
Perhaps
char *downcase_copy(const char *str)
{
char *copy = xmalloc(strlen(str) + 1);
int i;
for (i = 0; str[i]; i++)
copy[i] = tolower(str[i]);
copy[i] = '\0';
return copy;
}
may avoid having to copy things twice. Do you need the other
function exposed?
