MAT_GETFILEACCESSMODE(3)

💖 MAT_GETFILEACCESSMODE 💖

okay bestie, sit down, we're doing a Library Functions Manual moment and it's lowkey one of the cutest little functions in matio — it's giving "just tell me what mode this file is in" energy and honestly? iconic.

---

✨ NAME ✨

Mat_GetFileAccessMode — returns the file access mode of a MATLAB MAT file given a MAT file structure 🫶

---

🌸 SYNOPSIS 🌸

#include <matio.h>

enum mat_acc
Mat_GetFileAccessMode(const mat_t *matfp);

---

🦋 DESCRIPTION 🦋

so the Mat_GetFileAccessMode() function does exactly what it says on the tin, no cap: it hands you back the file access mode of the MATLAB MAT file that's described by the MAT file structure you pass in.

that's it. that's the whole vibe. you give it a MAT file structure, it tells you how that file is being accessed. periodt 💅

---

👑 RETURN VALUES 👑

the return value is one of these two, and there is no third option, fr fr:

• MAT_ACC_RDONLY — you get this if the file is opened with read-only access, or if it's not opened at all 🙈 (yes bestie, "never even opened" counts as read-only here, that's just how it is)
• MAT_ACC_RDWR — you get this if the file is opened with read/write access 🔥

so if you're sitting there like "wait, is this thing writable?" — this function is literally the vibe check you need 💀
