✨ veml6046x00_wait_data_available — bestie's guide to the Kernel API Manual ✨

okay so like. hi. welcome to the manual page for veml6046x00_wait_data_available(9), straight out of the Kernel API Manual, and honestly she's a short one but she delivers. this is the little function that sits there refreshing the vibe check until your sensor finally has something to say. no cap. 🎀

💅 NAME

veml6046x00_wait_data_available — wait until data is available. literally that's it, that's the whole job, and she does it iconically.

🌸 SYNOPSIS

int veml6046x00_wait_data_available (struct iio_dev *iio , unsigned int
usecs );

two args, one int coming back at you. we love a simple signature. 🫶

🦋 ARGUMENTS

• iio — Industrial IO. that's the device handle bestie, the whole IIO situation. ✨
• usecs — how many microseconds you're willing to wait for data. your patience, in tiny time units. ⏳

🔥 DESCRIPTION

so here's the tea: this function waits for a certain bit in the interrupt register — the one that's basically screaming "hey!! there's data to be read!! available!! right here!!" 📣

and the way she does it? she tries it two times, with a waiting time of usecs in between. so it's give-it-a-go, wait, give-it-another-go. lowkey stubborn, highkey effective. 💜

👑 RETURN

• 1 — data is available (AF_DATA_READY is set). yay!! she ate!! 🔥
• 0 — timeout, no data available after usecs timeout. 💀 sad but honest.
• -EIO — error during bulk read. 😭 the read did not go well, bestie.
