🌸 NAME 🌸

Mat_GetDir — returns a list of the variable names of a MATLAB MAT file given a MAT file structure 🦋

like, you hand her the MAT file structure, she hands you back the names of everything chillin' in there. no cap. 💅

---

✨ SYNOPSIS ✨

#include <matio.h>

char * const *
Mat_GetDir(mat_t *matfp, size_t *n);

she takes mat_t *matfp (your MAT file structure, bestie) and a size_t *n pointer, and she returns a char * const *. the way that signature is so specific and she knows it. 👑

💜 DESCRIPTION 💜

so, the Mat_GetDir() function returns a list of the variable names of a MATLAB MAT file given the MAT file structure. 📋✨

the output argument n holds the number of variables of the MATLAB MAT file. like, she's not just giving you the names — she's also telling you how many there are, through n. two-for-one, we love a multitasker. 🙈💖

lowkey important: n is an output argument, so she's writing into it, not reading from it. don't come for her. 😭

---

🌈 RETURN VALUES 🌈

the function returns a read-only list of the variable names of a MATLAB MAT file. 🔒📝

read-only. so look, admire, vibe with it — but do not try to edit it, bestie, she said what she said. ✋💅

and that's the whole page!! she's short, she's sweet, she's giving "small function, big main character energy." 🌟

this one came out of the Debian build of the manual, dated April 24, 2024 — so if you're reading this, mwah, thanks for stopping by, go name some variables. 🫶💖✨🍓

🎀 see you next time, bestie 🎀
