The above is the only assignment to namelen in this function, and
namelen is used like so:
if (name) {
...
pos = index_name_pos(&the_index, name, namelen);
So somebody does not realize that skip_prefix() returns true only
when it touches name. But skip_prefix() is inline and visible to
the compiler, and it is quite clear that name is only touched when
the function returns non-zero.
static inline int skip_prefix(const char *str, const char *prefix,
const char **out)
{
do {
if (!*prefix) {
*out = str;
return 1;
}
} while (*str++ == *prefix++);
return 0;
}
So it looks like it is another case of compiler getting confused.
