Is val always longer than 5 or 6 bytes here?


That does not matter, since they are strings, and the memcmp should not look further if they are shorter (because the comparison to '\0' failed already).


That's what strcmp() does. memcmp() walks the lenghth even if it encounters nul bytes. Perhaps you confuse it with strncmp()?


However, if !memcmp("imaps:", val, 6), it means that val starts with the string "imaps:", right? Then !memcmp("imap:", val, 5) must always fail, no?


Yes. Recent gcc's will recognize it as dead code and remove it. It's still ugly though.
