AuWriteElement(3)

💖 AuWriteElement(3) — the audiolib glow-up 💖

okay bestie, sit down, hydrate, and let's talk about AuWriteElement from the audiolib manual (Network Audio System C Language Interface, iykyk). this is the function that pushes your actual audio data into a flow. it's giving data pipeline main character energy. 🌊

✨ Name ✨

AuWriteElement — write data to an ImportClient element in a flow. that's it, that's the vibe. 💅

---

🌸 Synopsis 🌸

#include <audio/audiolib.h>

void AuWriteElement(server, flow, element, num_bytes, data, end_of_data,
status)
    AuServer *server;
    AuFlowID flow;
    int element;
    AuUint32 num_bytes;
    AuPointer data;
    AuBool end_of_data;
    AuStatus *status; /* RETURN */

look at that signature. she's structured, she's typed, she's organized. 🎀

🦋 Arguments 🦋

• server — the connection to the audio server. your little handshake with the mothership. 🛸
• flow — the ID of the flow. which flow, bestie? this flow.
• element — the index of the ImportClient element you're writing the data to. gotta point at the right one, no guessing. 👀
• num_bytes — how many bytes of audio data you're writing. count them. respect them.
• data — the buffer you're pulling the audio data from. the source of truth. the supply. 📦
• end_of_data — tells everyone whether this is the last write for this import. the final send. the mic drop. 🎤
• status — if it's non-NULL, the output buffer gets flushed and the status from the server comes back to you. it's marked /* RETURN */, so like, she reports back. 💌

💜 Description 💜

so what does AuWriteElement actually do? it transfers audio data from the client application to the server. that's the whole arc. 🫶

specifically: it writes num_bytes from data into the ImportClient specified by element, inside the audio flow flow.

and if end_of_data is AuTrue, the ImportClient's eof flag gets set once the write is done. closure, but make it technical. ✨

---

👑 Note 👑

if the flow is "trivial" — meaning it consists only of an ImportClient and an ExportBucket — then the num_samples fields in the ImportClient and ExportBucket are ignored. 😭 and bestie, if you write past the end of the bucket, you get an AuBadLength error. so like. know where the bucket ends. respectfully. 💀

💀 Errors 💀

• AuBadFlow
• AuBadElement
• AuBadValue
• AuBadLength

four little ways for things to go sideways. we don't gatekeep. 🙈
