TDB_DELETE(3)

💖 TDB_DELETE 💖

okay bestie, welcome to tdb_delete — it's from the Linux Programmer's Manual (section 3, we're fancy like that 💅), and it's the part where we yeet a record straight out of a tdb database. no takebacks, no receipts.

---

✨ NAME ✨

tdb_delete — delete a record from a tdb database. that's it. that's the whole job. she's a one-task queen 👑

---

🌸 SYNOPSIS 🌸

#include <tdb.h>

int tdb_delete(TDB_CONTEXT *tdb, TDB_DATA key);

like… two args, one int back. lowkey elegant, highkey iconic.

---

🦋 DESCRIPTION 🦋

so here's the vibe: you hand her a key, she finds the record in the tdb database whose key matches it, and she deletes it. gone. bye. 🫶

and what even is a key? it's a lump of data that is used as the index into the database. that's the whole concept — a blob of bytes doing the job of a lookup tag. no cap.

the TDB_DATA structure is defined as:

typedef struct {
     char *dptr;
     size_t dsize;
} TDB_DATA;

so dptr is your pointer to the data and dsize is how big it is. pointer plus length, the classic duo, the main character energy pairing of C 💀

⭐ RETURN VALUE ⭐

• 0 — success, we ate, the record is deleted 🎀
• -1 — failure, it's giving sad girl hours 😭

that's the entire scale. binary. no in-between. periodt.
