RPC(3N)

NAME
rpc - library routines for remote procedure calls

DESCRIPTION
These routines allow C programs to make procedure calls on other machines across the network. First, the client calls a procedure to send a data packet to the server. Upon receipt of the packet, the server calls a dispatch routine to perform the requested service, and then sends back a reply. Finally, the procedure call returns to the client.

FUNCTIONS
auth_destroy()	destroy authentication information handle
authnone_create()	return RPC authentication handle with no checking
authunix_create()	return RPC authentication handle with UNIX permissions
authunix_create_default()	return default UNIX authentication handle
callrpc()	call remote procedure, given [prognum,versnum,procnum]
clnt_broadcast()	broadcast remote procedure call everywhere
clnt_call()	call remote procedure associated with client handle
clnt_destroy()	destroy client's RPC handle
clnt_freeres()	free data allocated by RPC/XDR system when decoding results
clnt_geterr()	copy error information from client handle to error structure
clnt_pcreateerror()	print message to stderr about why client handle creation failed
clnt_perrno()	print message to stderr corresponding to condition given
clnt_perror()	print message to stderr about why RPC call failed
clntraw_create()	create toy RPC client for simulation
clnttcp_create()	create RPC client using TCP transport

get_myaddress() 	get the machine's IP address
pmap_getmaps()	return list of RPC program-to-port mappings
pmap_getport()	return port number on which waits supporting service
pmap_rmtcall()	instructs portmapper to make an RPC call
pmap_set()	establish mapping between [prognum,versnum,procnum] and port
pmap_unset()	destroy mapping between [prognum,versnum,procnum] and port
registerrpc()	register procedure with RPC service package
rpc_createerr	global variable indicating reason why client creation failed
svc_destroy()	destroy RPC service transport handle
svc_fds 	global variable with RPC service file descriptor mask
svc_freeargs()	free data allocated by RPC/XDR system when decoding arguments
svc_getargs()	decodes the arguments of an RPC request
svc_getcaller()	get the network address of the caller of a procedure
svc_getreq()	returns when all associated sockets have been serviced
svc_register()	associates prognum and versnum with service dispatch procedure
svc_run()	wait for RPC requests to arrive and call appropriate service
svc_sendreply()	send back results of a remote procedure call
svc_unregister()	remove mapping of [prognum,versnum] to dispatch routines
svcerr_auth()	called when refusing service because of authentication error
svcerr_decode()	called when service cannot decode its parameters
svcerr_noproc()	called when service hasn't implemented the desired procedure
svcerr_noprog()	called when program is not registered with RPC package
svcerr_progvers()	called when version is not registered with RPC package
svcerr_systemerr()	called when service detects system error
