🌸 __iucv_message_receive (9) — Kernel API Manual 💅

okay so bestie, welcome to the Kernel API Manual, section 9, and today's main character is __iucv_message_receive. she receives messages. she does NOT do locking. we stan a low-maintenance icon ✨

✨ NAME ✨

__iucv_message_receive — Receives messages on an established path (no locking) 🎀

like yes, that's the whole vibe: messages come in on a path you already established, and she does not lock anything. not her job. not her problem. periodt.

🦋 SYNOPSIS 🦋

int __iucv_message_receive (struct iucv_path *path , struct iucv_message
*msg , u8 flags , void *buffer , size_t size , size_t *residual );

look at that signature. gorgeous. iconic. returns an int, takes six whole arguments, and one of them is literally a size_t *residual so you will be getting a pointer back, no cap 💖

🎀 ARGUMENTS 🎀

  • path — address of iucv path structure. this is your established path, the little road the messages travel on 🛣️
  • msg — address of iucv msg structure. the message itself lives here 🫶
  • flags — flags that affect how the message is received. the one flag named here is IUCV_IPBUFLST ⭐
  • buffer — address of data buffer, or address of struct iucv_array. yes, she's flexible like that — either a plain buffer or an array struct 🔥
  • size — length of data buffer. keep it accurate or, like, don't 😭
  • residual — bestie the original manpage literally gives no description here, so I'm not about to invent one for you. it's a parameter, it's listed, that's what we know 🙈

💜 DESCRIPTION 💜

so here's the tea ☕ — this function receives messages that are being sent to you over established paths. that's it, that's the job, and she does it well 👑

and the extra slay? she will also deal with RMDATA messages embedded in struct iucv_message as well. so those little embedded ones don't get to sneak past her. not on her watch 💅

Locking: no locking 🚨

like, for real, none. so if you were expecting her to hold a lock for you, she is not that girl. you handle that yourself, bestie. iykyk.

🌈 RETURN 🌈

the result from the CP IUCV call. she's not out here making up her own return values, she just hands you back whatever CP IUCV said. honest queen 🫶
