SDL_CD(3)

💿 SDL_CD(3) — CDROM Drive Information ✨

okay bestie, gather round — this is the SDL_CD page from the SDL API Reference, and it's literally all about peeking inside a CD-ROM drive. let's get into it 🎀

---

🦋 STRUCTURE DEFINITION

typedef struct{
  int id;
  CDstatus status;
  int numtracks;
  int cur_track;
  int cur_frame;
  SDL_CDtrack track[SDL_MAX_TRACKS+1];
} SDL_CD;

that's the whole struct, no cap. 💅

---

🌸 STRUCTURE DATA

so here's what every single field is doing in there, bestie:

• id — private drive identifier 🆔 (it's giving mysterious, it's giving "don't touch, it's mine")
• status — drive status 🚦 (how's the drive doing today)
• numtracks — number of tracks on the CD 🎵
• cur_track — current track 📍
• cur_frame — current frame offset within the track 🎯
• track[SDL_MAX_TRACKS+1] — array of track descriptions, like a lil roster of every track. (see SDL_CDtrack) 📋

💖 DESCRIPTION

so an SDL_CD structure gets returned by SDL_CDOpen. it's the representation of an opened CDROM device, and it stores all the info about how the tracks on the disc are laid out. very demure, very mindful. 🫶

now, a frame? that's the base data unit of a CD, periodt. CD_FPS frames equals 1 second of music — that's the conversion rate, remember it. 🌈

and SDL is nice enough to hand you two macros for converting between time and frames: FRAMES_TO_MSF(f, M,S,F) and MSF_TO_FRAMES. go off, math. ✨

---

🎀 EXAMPLES

here's how it looks in action, bestie:

int min, sec, frame;
int frame_offset;

FRAMES_TO_MSF(cdrom->cur_frame, &min, &sec, &frame);
printf("Current Position: %d minutes, %d seconds, %d frames
", min, sec, frame);

frame_offset=MSF_TO_FRAMES(min, sec, frame);

look at that. converting the current frame into minutes/seconds/frames and back again. it's giving main character energy. 👑
