AuGetElementStates(3)

💖 AuGetElementStates — the audiolib library functions manual, but make it cute 💖

okay bestie, so this one lives in the audiolib manual (that's the Network Audio System C Language Interface, iykyk) and it's literally about peeking at what your flow elements are up to. getting the receipts on your elements, fr fr.

🌸 NAME 🌸

AuGetElementStates — get the state of elements in a flow

like… you wanna know what those elements are doing? this is the function. no cap.

---

✨ SYNOPSIS ✨

#include <audio/audiolib.h>

AuElementState *AuGetElementStates(server, num_states, states, status)
    AuServer *server;
    int *num_states; /* SEND and RETURN */
    AuElementState *states;
    AuStatus *status; /* RETURN */

look at her. she's giving "returns a pointer to a whole list of element states". 💅

🎀 ARGUMENTS 🎀

• server — the connection to the audio server. your little link to the audio mothership, basically. 🛰️
• num_states — on the way in, this says how many element states are chillin' in states. on the way out, it gets updated to tell you how many element states actually came back. so it's doing double duty, and honestly? obsessed with her work ethic. (it's marked SEND and RETURN for exactly that reason, bestie.)
• states — the list of AuElementState structures you're passing in. each one points at the flow and the element number of an element whose state you want back. like a lil shopping list but for element states. 🛍️
• status — if this isn't NULL, the output buffer gets flushed and the status from the server gets returned right here. if it is NULL, nothing happens, no stress. (marked RETURN, obviously.)

---

🦋 DESCRIPTION 🦋

AuGetElementStates returns a list of element states. that's the main character move. 🎬

but here's the thing — if there was an error, it returns NULL instead, and num_states gets set to 0. so like, if you get nothing back and a zero, that's not a vibe check failure, that's just an error being an error. 😭

and when you're done with that list? use AuFreeElementStates to free it when it's no longer needed. clean up after yourself, queen. leaving memory lying around is not it. 🧹✨

---

👑 NOTES 👑

⚠️ trying to get the state of a non-component element will result in an error. the non-component elements are: AddConstant, Bundle, ExportMonitor, MultiplyConstant, and Sum. don't do it. it's not gonna slay, it's gonna error.

💀 ERRORS 💀

these are the ones that can come at you:

• AuBadFlow
• AuBadLength
• AuBadAlloc
• AuBadElement

okay that's the whole page, bestie!! now go forth and get those element states. 🍓🧚💜

this was audiolib - flow elements states, version 1.9.4, and the page is AuGetElementStates(3) — mwah, periodt. 💅✨
