(OBSOLETE)

mapping of the triple [prognum , versnum , protocol ]toxprt

→xp_port is established with the

local

portmap service (generally, protocol is 0

, IPPROTO_UDP,orIPPROTO_TCP). The pro-

cedure dispatch has the following form:

dispatch(struct svc_req *

request , SVCXPRT *xprt);

The svc_register()

routine returns 1 if it succeeds, and 0 otherwise.

Warning: this routine exists for backward compatibility only; enhanced functionality is pro-

vided by

svc_reg() (see rpc_svc_calls(3N)).

void svc_unregister()

Remove all mapping of the double [prognum, versnum ] to dispatch routines, and of the triple

[prognum, versnum, all-protocols] to port number from

portmap.

Warning: this routine exists for backward compatibility, enhanced functionality is provided by

svc_unreg() (see rpc_svc_calls(3N)).

xdr_authunix_parms()

Used for describing UNIX credentials. This routine is useful for users who wish to generate

these credentials without using the RPC authentication package.

Warning: this routine exists for backward compatibility only, and is made obsolete by

xdr_authsys_parms()

(see rpc_xdr (3N)).
