🌸 ctucan_is_txt_buf_writable(9) 🌸

Okay so welcome to this little page from the Kernel API Manual, bestie. We're checking out ctucan_is_txt_buf_writable, and it's literally a vibe check for a frame trying to get into the TXT Buffer. 💅✨

🎀 NAME 🎀

ctucan_is_txt_buf_writable — checks if a frame can be inserted to the TXT Buffer. No cap. 💖

✨ SYNOPSIS ✨

bool ctucan_is_txt_buf_writable (struct ctucan_priv *priv , u8 buf );

🫶 ARGUMENTS 🫶

• priv — pointer to private data. This is the context, bestie, the private-data pointer. 🔥
• buf — buffer index, and it's 0-based. So the first one is 0, iykyk. ✨

👑 RETURN 👑

• True — frame can be inserted to the TXT Buffer. Slay, it's allowed in. 🎀
• False — if attempted, frame will not be inserted to the TXT Buffer. Not me getting rejected at the door 😭💀
