svc_find_xprt(9)

💖 svc_find_xprt(9) 💖

okay bestie, this page is from the Kernel API Manual, and it's literally about finding an RPC transport instance. it's giving “where is that transport at?” energy, no cap. 🎀✨

🎀 NAME 🎀

svc_find_xprt — find an RPC transport instance. that's the whole name, bestie. 💅

✨ SYNOPSIS ✨

struct svc_xprt * svc_find_xprt (struct svc_serv *serv , const char
       *xcl_name , struct net *net , const sa_family_t af , const unsigned
       short port );

🫶 ARGUMENTS 🫶

• serv — pointer to svc_serv to search. yes, the service struct you're searching through. 🔍
• xcl_name — C string containing transport's class name.
• net — owner net pointer.
• af — Address family of transport's local address.
• port — transport's IP port number. the port, periodt. 💅

💅 DESCRIPTION 💅

so, like, svc_find_xprt returns the transport instance pointer for the endpoint accepting connections/peer traffic from the specified transport class, address family and port. yes, that's the whole quest. 🦋

and the wildcard part is iconic: specifying 0 for the address family or port is effectively a wild-card, and will result in matching the first transport in the service's list that has a matching class name. so 0 means “idc, first match with the same class name wins.” periodt. 💀✨
