epout_has_pkt(9)

🌸 NAME 🌸

epout_has_pkt - checks if OUT endpoint fifo has a packet available.

This is the epout_has_pkt(9) page from the Kernel API Manual, and yes bestie, it's a tiny one — but every crumb matters. 🫶

✨ SYNOPSIS ✨

The signature, exactly as it is:

int epout_has_pkt (struct pxa_ep *ep );

🎀 ARGUMENTS 🎀

• ep — pxa endpoint. That's the only argument, no cap. 💅

💖 DESCRIPTION 💖

Returns 1 if a complete packet is available, 0 if not, and -EOPNOTSUPP for IN ep. That's the whole vibe check — no extra lore, just the return values doing their lil thing. ✨
