Man page 9 : svc_find_xprt

svc_find_xprt - find an RPC transport instance

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 );

serv
    pointer to svc_serv to search

xcl_name
    C string containing transportAqs class name

net
    owner net pointer

af
    Address family of transportAqs local address

port
    transportAqs IP port number

Return the transport instance pointer for the endpoint accepting connections/peer traffic from the specified transport class, address family and port.

Specifying 0 for the address family or port is effectively a wild-card, and will result in matching the first transport in the serviceAqs list that has a matching class name.
