RPC_GSS_SVC_MAX_DATA_LENGTH(3t)

✨ NAME ✨

okay so this is rpc_gss_svc_max_data_length — and bestie, the whole entire job of this function is calculating maximum data size 💖 that's it, that's the gig, she does the math so you don't have to 🧮✨

(fr fr, it's a Library Functions Manual page, section 3, so it's a library call — not a command you type in your shell, iykyk 🫶)

🌸 SYNOPSIS 🌸

#include <rpc/rpcsec_gss.h>

int
rpc_gss_svc_max_data_length(struct svc_req *req, int max_tp_unit_len);

like, that's the whole signature. she's a little one. she's an icon 👑

🦋 DESCRIPTION 🦋

okay so here's the vibe 💅

rpc_gss_svc_max_data_length() figures out the maximum message size that will fit into a packet of size max_tp_unit_len, given the current service and QoP setting.

that's literally it. you tell her how big the packet can be, she takes into account what service and QoP you've got going on right now, and she hands you back the biggest message that's gonna squeeze in there without spilling out the sides 🎀 no cap, that's the whole function.

💜 PARAMETERS 💜

• req — An RPC request 🫶 like, the actual request you're working with.
• max_tp_unit_len — Maximum packet size of the underlying transport protocol 📦 that's your ceiling, your limit, your "this is how much room we have to work with."

⭐ RETURN VALUES ⭐

she returns the maximum message size that can be encoded ✨

that's it. that's the return. no sneaky extra behaviour, just the number you asked for 💖

okay bestie that's the whole page, we ate and left no crumbs 🍓✨ this was Debian's page from January 26, 2010, filed under RPC_GSS_SVC_MAX_DATA_LENGTH(3) — and yes the title says RPC_GSS_SVC_MAX_DATA_LEN(3) up top, that's just the short version, don't stress it 💀 mwah, go compute your max message size, main character 🫶👑
