opus_types.h(3)

🌸 NAME 🌸

opus_types.h — bestie, this is the Opus reference implementation types header 💖 it's literally just the little squad of integer types that the whole Opus codebase rolls with, and it's in the opus_types.h(3) page of the Opus manual, so. yeah. that's the vibe check 👑

✨ SYNOPSIS ✨

okay so here's the whole cast, no notes 🎀

💅 Macros

#define opus_int   int                     /* used for counters etc; at
    least 16 bits */
#define opus_int64   long long
#define opus_int8   signed char
#define opus_uint   unsigned int            /* used for counters etc; at
    least 16 bits */
#define opus_uint64   unsigned long long
#define opus_uint8   unsigned char

🦋 Typedefs

typedef short opus_int16
typedef unsigned short opus_uint16
typedef int opus_int32
typedef unsigned int opus_uint32

🫶 Detailed Description 🫶

Opus reference implementation types. that's it, that's the whole description, she's short but she's iconic 💖 every int in the Opus source is basically cosplaying as one of these. periodt.

👑 Macro Definition Documentation 👑

💖 #define opus_int int /* used for counters etc; at least 16 bits */

the everyday counter type bestie 🎀 it's just int, and it's at least 16 bits, so use it for counters and stuff like that. nothing fancy, just reliable ✨

💖 #define opus_int64 long long

the big-girl signed integer 💅 that's long long, for when 32 bits simply cannot contain your feelings 😭

💖 #define opus_int64 long long ... wait no 🌸

okay actual next one: #define opus_int8 signed char — the tiniest signed baby 🍓 literally just signed char, one little byte of drama.

💖 #define opus_uint unsigned int /* used for counters etc; at least 16 bits */

the unsigned twin of opus_int 🦋 it's unsigned int, again at least 16 bits, and again used for counters etc. same energy, no negativity allowed 💜

💖 #define opus_uint64 unsigned long long

unsigned, sixty-four bits, unsigned long long — the big one that never goes negative 🧚 slay.

💖 #define opus_uint8 unsigned char

unsigned char ✨ the lil one-byte unsigned cutie. no sign, no problems, just vibes 🌈

⭐ Typedef Documentation ⭐

these are the actual typedefs, bestie, the named ones you'll see all over the Opus code 🎀

• typedef short opus_int16 — 16-bit signed, lowkey just short 💖
• typedef int opus_int32 — 32-bit signed, which is literally int 😭 iconic
• typedef unsigned short opus_uint16 — 16-bit unsigned, aka unsigned short 🦋
• typedef unsigned int opus_uint32 — 32-bit unsigned, aka unsigned int, the moment 💅

ngl there's no opus_int16-style magic going on under the hood — these typedefs are exactly the C types they say they are, so don't go expecting any surprises 👑
