Function Compatibility Lists

This section lists the RPC library functions and groups them into functional areas. Each section includes lists of functions that are unchanged, have added functionality, and are new to this release.

Functions marked with an asterisk are retained for ease of porting.

Creating and Destroying Services

The following functions are unchanged from the previous releases and are available in the current SunOS release:1

svc_destroy
svcfd_create
*svc_raw_create
*svc_tp_create
*svcudp_create
*svc_udp_bufcreate
svc_create
svc_dg_create
svc_fd_create
svc_raw_create
svc_tli_create
svc_tp_create
svc_vc_create

Registering and Unregistering Services

The following functions are unchanged from the previous releases and are available in the current SunOS release:

*registerrpc
*svc_register
*svc_unregister
xprt_register
xprt_unregister
rpc_reg
svc_reg
svc_unreg

SunOS Compatibility Calls

The following functions are unchanged from previous releases and are available in the current SunOS release:

*callrpc
clnt_call
*svc_getcaller - works only with IP-based transports
rpc_call
svc_getrpccaller

Broadcasting

The clnt_broadcast call has the same functionality as in previous releases, although it is supported for backward compatibility only.

clnt_broadcast() can broadcast only to the portmap service. It does not support rpcbind.

The rpc_broadcast function broadcasts to both portmap and rpcbind and is also available in the current SunOS release.

Address Management Functions

The TI-RPC library functions interface with either portmap or rpcbind. Because the services of the programs differ, there are two sets of functions, one for each service.

The following functions work with portmap:

pmap_set
pmap_unset
pmap_getport
pmap_getmaps
pmap_rmtcall

The following functions work with rpcbind:

rpcb_set
rpcb_unset
rpcb_getaddr
rpcb_getmaps
rpcb_rmtcall

Authentication Functions

The following calls have the same functionality as in previous releases. They are supported for backward compatibility only.

authdes_create
authunix_create
authunix_create_default
authdes_seccreate
authsys_create
authsys_create_default

Other Functions

rpcbind provides a time service, primarily for use by secure RPC client-server time synchronization, available through the rpcb_gettime() function. pmap_getport() and rpcb_getaddr() can be used to get the port number of a registered service. rpcb_getaddr() communicates with any server running version 2, 3, or 4 of rcpbind. pmap_getport() can only communicate with version 2.
