TAB(3)

💅 TAB(3) — Library Functions Manual 💅

okay bestie, this is TAB(3) from the Library Functions Manual — the simple table lookup routines chapter, and it’s lowkey iconic in a “tiny lookup table” way. 🫶

✨ NAME ✨

tab — simple table lookup routines

🎀 SYNOPSIS 🎀

#include <ast.h>

int tabindex(const void* tab, int size, const char* name); void*
tablook(const void* tab, int size, const char* name);

💖 DESCRIPTION 💖

so these routines are doing linear lookups in small tables — like, on the order of 32 elements, not some giant main-character database. 💀

Each table element has a size of size bytes, and the beginning of the element points to a name that gets matched by the lookup routines. that’s the whole shape of it, no cap. 🦋

• tabindex — returns the index of the table element in tab that matches name. if there’s no match, it returns -1 (rip, not found 😭).
• tablook — returns a pointer to the table element in tab that matches name. if there’s no match, it returns 0 (empty-handed bestie 🙈).

🦋 SEE ALSO 🦋

• hash(3)

k byeee — that’s TAB(3) from the Library Functions Manual. 💖 the footer is literally just TAB(3); no source/version/date line to report on this one, so that’s the whole tea. 🫶
