hdf_set_buf(3)

💖 hdf_set_buf(3) 💖

okay so bestie, this one lives in util/neo_hdf.h and it's giving memory management but make it a gift. no cap.

✨ NAME ✨

hdf_set_buf — set the value of a node, but like… without duplicating the value 🫶

🌸 SYNOPSIS 🌸

#include <util/neo_hdf.h>

NEOERR* hdf_set_buf (HDF *hdf, const char *name, char *value);

🎀 ARGUMENTS 🎀

• hdf — the hdf dataset node, the main character we're walking through 💅
• name — the name you wanna walk to, literally the lil path
• value — the malloc'd value, and yes it HAS to be malloc'd, we're getting to that 👑

🦋 DESCRIPTION 🦋

so hdf_set_buf is basically hdf_set_value's chaotic twin. they're similar, sure, but here's the plot twist: the dataset takes ownership of the value instead of making a copy of it. no dupe, no photocopy, we're handing over the actual thing 😭

and because the dataset now owns it, the dataset assumes that value was malloc'd — since it will attempt to free it when hdf_destroy is called. so fr fr, do not pass it something that didn't come from malloc, because that free is coming whether you're ready or not 💀

⭐ RETURN VALUE ⭐

None. that's it, that's the whole thing. nothing returned, we move 💖

⚠️ real talk though: only pass a value that was malloc'd. the dataset is gonna free it later and it is NOT gonna ask permission first. that's not a vibe check you wanna fail 😭
