MAT_VARDELETE(3)

✨ MAT_VARDELETE(3) ✨

okay bestie, pull up a chair 💖 this is a page from the Library Functions Manual, and it's about one very specific little function that does one very specific little thing. no cap.

---

🎀 NAME 🎀

Mat_VarDelete — deletes a MAT variable from a file. that's it. that's the whole job. she's a simple queen and she knows it 💅

---

🌸 SYNOPSIS 🌸

#include <matio.h>

int
Mat_VarDelete(mat_t *matfp, const char *name);

look at her. two arguments. no drama. iconic. ✨

---

🦋 DESCRIPTION 🦋

so the way that this works is: Mat_VarDelete() takes the MAT variable called name and deletes it from the MAT file that's represented by the MAT file structure matfp. 🗑️✨

that's it!! it goes in, it finds the variable by name, and it's gone. not me being emotionally attached to a variable, couldn't be me 🙈

---

💜 RETURN VALUES 💜

• 0 — success, we ate, no crumbs, the variable is deleted 💅
• anything else — an error value gets returned instead 😭 something went sideways

bestie, the manual is very chill about it and just says "an error value is returned" — so like, don't assume it's a specific number, okay? check that it's 0 and you're golden. 👑

and that's the whole page, periodt. 🫶
