rpc_pton(9)

💖 NAME 💖

rpc_pton — Construct a sockaddr in @sap ✨

Okay bestie, this is the rpc_pton(9) page from the Kernel API Manual, and it’s here to teach you how this function constructs a sockaddr in @sap. Not me being dramatic, it’s literally the name. 💅

🌸 SYNOPSIS 🌸

size_t rpc_pton (struct net *net , const char *buf , const size_t buflen
       , struct sockaddr *sap , const size_t salen );

🎀 ARGUMENTS 🎀

• net — applicable network namespace.
• buf — C string containing presentation format IP address.
• buflen — length of presentation address in bytes.
• sap — buffer into which to plant socket address.
• salen — size of buffer in bytes.

🦋 DESCRIPTION 🦋

So here’s the vibe: this function returns the size of the socket address if it’s successful; otherwise zero is returned. That’s the success/failure check, no cap.

It plants a socket address in sap and returns the size of the socket address, if successful. Returns zero if an error occurred. Literally that simple: happy path gives you the size, error path gives you 0 and you can go touch grass. 😭
