✨ AuReadElement ✨

okay bestie, gather round, because today we're talking about AuReadElement(3) — it lives in the Library Functions Manual and it's literally the "gimme that audio data" function. it's giving read from an ExportClient element in a flow. no cap. 🎀

🌸 NAME 🌸

AuReadElement — read data from an ExportClient element in a flow 💖

🦋 SYNOPSIS 🦋

#include <audio/audiolib.h>

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

💅 ARGUMENTS 💅

  • server — the connection to the audio server. that's your link-up, your main character connection. 🔥
  • flow — the ID of the flow. yes bestie, the flow it's reading from. 🌊
  • element — the index of the ExportClient element you're pulling the data out of. gotta point at the right one, okay? 🎯
  • num_bytes — how many bytes of audio data you wanna read. exactly that many, not vibes-based. 📏
  • data — the buffer you're reading the audio data into. your lil container. 🍓
  • status — if it's non-NULL, it flushes the output buffer and returns the status from the server. if it's NULL, no status for you, sorry. 🙈

✨ DESCRIPTION ✨

okay so here's the tea: AuReadElement transfers audio data from the server to the client application. it reads num_bytes from the ExportClient that's specified by element, inside the audio flow flow, and drops it all into data. that's the whole job. she's focused, she's iconic, she slays. 👑

🎀 NOTE 🎀

heads up bestie! if the flow is "trivial" — meaning it's literally just an ExportClient and an ImportBucket, nothing else — then the num_samples fields in the ExportClient and the ImportBucket are ignored. like, they don't even get looked at. 💀

💀 ERRORS 💀

  • AuBadFlow
  • AuBadElement

(these are the "something's not right" girls. if you see one, check your flow and your element index. 🫶)

and that's the whole page, babe! this gem is from audiolib — described as "read from element" — version 1.9.4, and it's the AuReadElement(3) page. go read some bytes, you've got this. 💖✨🦋
