✨ svc_print_xprts(9) ✨

okay so this is a page from the Kernel API Manual, section 9, and bestie it is so specific it's almost cute. it's all about formatting a little transport list so you can actually print it. yes, that's the whole vibe. let's get into it 🎀

💖 NAME 💖

svc_print_xprts — literally formats the transport list so it's ready for printing 🖨️✨

🌸 SYNOPSIS 🌸

int svc_print_xprts (char *buf , int maxlen );

🦋 ARGUMENTS 🦋

  • buf — the target buffer where the formatted address goes, that's its whole job 🫶
  • maxlen — the length of that target buffer, so it knows how much room it's working with

⭐ DESCRIPTION ⭐

so basically it fills in buf with a string holding a list of transport names, and every single name is terminated with <hotpink>'0</hotpink>. that's the delimiter, no cap.

⚠️ heads up: if the buffer is too small, some entries may be missing — but here's the slay part: it is guaranteed that all lines in the output buffer are complete. so you might lose a whole entry, but you'll never get a half-finished one. iconic behaviour honestly 💅

it returns the positive length of the filled-in string. periodt. 💯
