💖 libolecf(3) 💖

okay so bestie, welcome to libolecf — a library that lets you open up the Object Linking and Embedding (OLE) Compound File (CF) format. yes THAT format. the one every old-timey Office doc is secretly made of. this is the Library Functions Manual for it, and we're gonna go through every single function together. no skimming, no skipping, i got you. 🫶

🌈 DESCRIPTION 🌈

ok so listen. the libolecf_get_version() function is used to retrieve the library version. that's it. that's the whole description. she's simple, she's iconic. 💅

---

💀 RETURN VALUES 💀

most of the functions return NULL or -1 on error, dependent on the return type. ngl it depends on what type you're getting back. for the actual return values, go look at "libolecf.h". iykyk. 📖

---

🌱 ENVIRONMENT 🌱

None

like literally nothing. no env vars. not a single one. periodt.

---

🗂️ FILES 🗂️

None

no files either bestie. she's self-contained. 🫶

---

📝 NOTES 📝

libolecf allows to be compiled with wide character support (wchar_t). ✨

to compile libolecf with wide character support use: ./configure --enable-wide-character-type=yes or define: _UNICODE or UNICODE during compilation.

LIBOLECF_WIDE_CHARACTER_TYPE in libolecf/features.h can be used to determine if libolecf was compiled with wide character support. 🕵️‍♀️

🐛 BUGS 🐛

please report bugs of any kind on the project issue tracker: https://github.com/libyal/libolecf/issues

do NOT be shy about it. they want to know. it's giving community. 💖
