Thank you. How about long returned from mio_tell and passed to mio_seek? I will introduce mio_long or mio_off_t. Is this acceptable?
We don't use MIO at all in Geany itself - its only use is through ctags and we don't call any of its API directly. So you can do whatever you want with it in ctags.
Historically, when MIO wasn't part of ctags, we used to replace all occurrences of `FILE` with `MIO` in ctags and pass the editor's buffer as MIO. But since MIO is now part of ctags, we just call
``` extern bool parseRawBuffer(const char *fileName, unsigned char *buffer, size_t bufferSize, const langType language, void *clientData) ```
and let ctags handle all the MIO stuff.
