AuMakeChangeStateAction(3)

✨ AuMakeChangeStateAction ✨

okay bestie, so this one is from audiolib — the Network Audio System C Language Interface, aka the library functions manual — and it's about making an action that changes a state. it's giving very "setup girlie" energy: you hand it a bunch of stuff, it fills in a lil struct for you. no cap. 💅

🎀 NAME 🎀

AuMakeChangeStateAction — initialize an action 💖

🌸 SYNOPSIS 🌸

#include <audio/audiolib.h>

AuMakeChangeStateAction(action, trigger_state, trigger_prev_state,
trigger_reason, flow, element_num, new_state)
    AuElementAction action; /* RETURN */
    unsigned char trigger_state;
    unsigned char trigger_prev_state;
    unsigned char trigger_reason;
    AuFlowID flow;
    unsigned char element_num;
    unsigned char new_state;

🦋 ARGUMENTS 🦋

• action — this one's the RETURN value, bestie. it hands you back the initialized action. ✨
• trigger_state — tells you which state is the one that triggers the action. it must be one of these constants: AuStateStop, AuStateStart, AuStatePause, or AuStateAny. pick one, no freelancing. 🙈
• trigger_prev_state — the previous state for the trigger. must be one of: AuStateStop, AuStateStart, AuStatePause, or AuStateAny. yes it's the same list, no i'm not messing with you. 🫶
• trigger_reason — the reason for the action. must be one of these constants: AuReasonUser, AuReasonUnderrun, AuReasonOverrun, AuReasonEOF, AuReasonWatermark, AuReasonHardware, or AuReasonAny. seven options, main character energy, choose wisely. 👑
• flow — the ID of the flow you're affecting. the flow. THE flow. ✨
• element_num — the index of the element to affect. it's an index, so like, numbers. 🔢
• new_state — the new state for the flow. must be one of these constants: AuStateStop, AuStateStart, or AuStatePause. notice that AuStateAny is NOT on this list — it's a real new state, not a vibe. 💀

💜 DESCRIPTION 💜

so AuMakeChangeStateAction sets the action field of action to AuElementActionChangeState and initializes all the other fields with the remaining arguments. that's it, that's the whole job. she's efficient. she ate. 🔥

also important: AuMakeChangeStateAction is implemented as a macro. so like, don't go taking its address or whatever, iykyk. 💅
