dbh_set_data(3)

✨ dbh_set_data — bestie edition ✨

okay so this is dbh_set_data(3), straight out of the DBHashTables Programmers' Manual 🫶 if you're here it's because you wanna write stuff into a record, and honestly? iconic of you. let's go 💅

---

🌸 NAME 🌸

dbh_set_data, dbh_set_key — setting the record data or the record key, no biggie, just your main character functions ✨

---

🎀 SYNOPSIS 🎀

#include <dbh.h>

void dbh_set_data (DBHashTable *dbh, void *data, FILE_POINTER size);

void dbh_set_key (DBHashTable *dbh, unsigned char *key);

---

💖 DESCRIPTION 💖

so dbh_set_data copies your user data into the current DBHashTable record. and when you pair it with dbh_set_key?? that's the moment the current DBHashTable record becomes ready — ready for the dbh_update function to commit it to the actual DBHashTable on disk. slay. 🔥

and if you only set the key? then the record is ready for dbh_load to load the current record data from disk instead. two paths, both valid, both giving ✨

about the args, fr fr:

• data — a pointer, and it's the spot where the data gets copied from into the current DBHashTable record. (so like, the source, bestie)
• size — literally just how many bytes to copy. that's it, that's the whole vibe. 🍓

and then dbh_set_key sets the key of the current DBHashTable record. simple, clean, doing its job 👑

---

💅 RETURN VALUE 💅

ngl these functions do not return anything. zero. nada. they just do the thing and dip. 😌

---

🦋 NOTES 🦋

okay important lil detail — the length of the key that gets copied? it's taken from the number of branches defined when the DBHashTable was created. so that number you picked way back at creation time? it's still the boss here. keep that in mind 🧠✨
