NAME

       rpc_svc_reg, rpc_reg, svc_reg, svc_unreg, svc_auth_reg, xprt_register, xprt_unregister - library routines for registering servers

DESCRIPTION

       These routines are a part of the RPC library which allows the RPC servers to register themselves with rpcbind() (see  rpcbind(1M)), and as-
       sociate the given program and version number with the dispatch function. When the RPC server receives a RPC request,  the  library  invokes
       the dispatch routine with the appropriate arguments.

   Routines
       See rpc(3NSL) for the definition of the	SVCXPRT data structure.

       #include <rpc/rpc.h>

       bool_t  rpc_reg(const  rpcprog_t  prognum,  const rpcvers_t versnum, const rpcproc_t procnum, char * (*procname)(), const xdrproc_t inproc,
       const xdrproc_t outproc, const char *nettype);

	   Register program prognum, procedure procname, and version versnum with the RPC service  package.  If  a  request  arrives  for  program
	   prognum,  version  versnum,	and  procedure	procnum,  procname  is called with a pointer to its parameter(s); procname should return a
	   pointer to its static result(s). The arg parameter to procname is a pointer to the (decoded) procedure  argument.  inproc  is  the  XDR
	   function  used  to decode the parameters while outproc is the XDR function used to encode the results. Procedures are registered on all
	   available transports of the class nettype. See rpc(3NSL). This routine returns 0 if the registration succeeded, -1 otherwise.

       int svc_reg(const SVCXPRT *xprt, const rpcprog_t prognum, const rpcvers_t versnum, const void (*dispatch)(), const struct  netconfig  *net-
       conf);

	   Associates  prognum	and  versnum with the service dispatch procedure, dispatch. If netconf is NULL, the service is not registered with
	   the rpcbind service.  For example, if a service has already been registered using some other means, such as inetd (see  inetd(1M)),	it
	   will  not  need  to	be registered again. If netconf is non-zero, then a mapping of the triple [prognum,  versnum, netconf->] to xprt->
	   xp_ltaddr is established with the local rpcbind service.

	   The svc_reg() routine returns 1 if it succeeds, and 0 otherwise.

       void svc_unreg(const rpcprog_t prognum, const rpcvers_t versnum);

	   Remove from the rpcbind service, all mappings of the triple [prognum, versnum, all-transports] to  network  address	and  all  mappings
	   within the RPC service package of the double [prognum, versnum] to dispatch routines.

       int svc_auth_reg(const int cred_flavor, const enum auth_stat (*handler)());

	   Registers the service authentication routine handler with the dispatch mechanism so that it can be invoked to authenticate RPC requests
	   received with authentication type cred_flavor. This interface allows developers to add new authentication types to their  RPC  applica-
	   tions without needing to modify the libraries. Service implementors usually do not need this routine.

	   Typical  service  application  would  call  svc_auth_reg() after registering the service and prior to calling svc_run(). When needed to
	   process an RPC credential of type cred_flavor, the handler procedure will be called with two parameters  (struct svc_req *rqst,  struct
	   rpc_msg  *msg) and is expected to return a valid enum auth_stat value. There is no provision to change or delete an authentication han-
	   dler once registered.

	   The svc_auth_reg() routine returns 0 if the registration is successful, 1 if cred_flavor already has an authentication  handler  regis-
	   tered for it, and -1 otherwise.

       void xprt_register(const SVCXPRT *xprt);

	   After  RPC  service	transport  handle xprt is created, it is registered with the RPC service package. This routine modifies the global
	   variable svc_fdset (see rpc_svc_calls(3NSL)). Service implementors usually do not need this routine.

       void xprt_unregister(const SVCXPRT *xprt);

	   Before an RPC service transport handle xprt is destroyed, it unregisters itself with the RPC service package. This routine modifies the
	   global variable svc_fdset (see rpc_svc_calls(3NSL)). Service implementors usually do not need this routine.
