✨ GETRPCPORT(3) ✨

okay so bestie, welcome to GETRPCPORT(3) — the Library Functions Manual page that's about to explain how to get an RPC port number 💖 no cap, it's giving very specific networking energy. Let's go 🎀

🌸 NAME 🌸

getrpcport — get RPC port number 👑

💅 SYNOPSIS 💅

int
getrpcport(char *host, int prognum, int versnum, int proto);

🦋 DESCRIPTION 🦋

okay so the getrpcport() function is literally here to return the port number for version versnum of the RPC program prognum running on host and using protocol proto. periodt. ✨

It returns 0 if it cannot contact the portmapper, or if prognum is not registered. 💀

If prognum is registered but not with version versnum, it will still return a port number (for some version of the program) indicating that the program is indeed registered. The version mismatch will be detected upon the first call to the service. 👀

🌈 AVAILABILITY 🌈

The getrpcport() function is part of libtirpc. slay. 💅

later bestie 🫶 this page is from Debian, dated October 6, 1987, and it's GETRPCPORT(3) 💖✨
