     MP4FileHandle hFile,
     MP4TrackId trackId
)

look at her. clean. no cap. include <mp4.h> and you're already halfway there 🦋

---

✨ ARGUMENTS ✨

• hFile — the mp4 file you want the operation to apply to. like, which file are we talking about, bestie? this one 🫶
• trackId — the track whose number of edit segments you're dying to know. point at the track, get the count. simple as that 💖

---

✨ RETURN VALUES ✨

• slay era: on success you get back the number of edit segments for the track. 🎀
• not slay era: on an error you get 0. that's the whole "something went wrong" signal. periodt. 😭

---

✨ DESCRIPTION ✨

MP4GetTrackNumberOfEdits returns the number of edit segments in the specified track in the mp4 file. literally exactly what it says on the tin 🧚

and here's the iconic part — the edit id's are the consecutive sequence of numbers from 1 to the total number of edit segments. that means 1-based indexing, not 0-based indexing. i know. i KNOW. not a single 0 in sight. she's quirky like that 💀

bestie reminder: if you're looping over edit ids, start at 1 and go up to the total. start at 0 and you will simply be lost in the sauce 🙈
