1 indicates that the out of -range request will be silently ignored. -.It Dv SVCSET_VERSQUIET -If a request is received for a program number -served by this server but the version number -is outside the range registered with the server, -an -.Dv RPC_PROGVERSMISMATCH -error will normally -be returned. -It is sometimes desirable to -change this behavior. -.Fa info -should be a -pointer to an integer which is either 0 -(indicating normal server behavior - an -.Dv RPC_PROGVERSMISMATCH -error will be returned), -or 1 (indicating that the out of range request -should be silently ignored). -.El -.It Fn svc_create -.Fn svc_create -creates server handles for all the transports -belonging to the class -.Fa nettype . -.Fa nettype -defines a class of transports which can be used -for a particular application. -The transports are tried in left to right order in -.Ev NETPATH -variable or in top to bottom order in the netconfig database. -If -.Fa nettype -is -.Dv NULL , -it defaults to -.Qq netpath . -.Pp -.Fn svc_create -registers itself with the rpcbind -service (see -.Xr rpcbind 8 ) . -.Fa dispatch -is called when there is a remote procedure call for the given -.Fa prognum -and -.Fa versnum ; -this requires calling -.Fn svc_run -(see -.Fn svc_run -in -.Xr rpc_svc_reg 3 ) . -If -.Fn svc_create -succeeds, it returns the number of server -handles it created, -otherwise it returns 0 and an error message is logged. -.It Fn svc_destroy -A function macro that destroys the RPC -service handle -.Fa xprt . -Destruction usually involves deallocation -of private data structures, -including -.Fa xprt -itself. -Use of -.Fa xprt -is undefined after calling this routine. -.It Fn svc_dg_create -This routine creates a connectionless RPC -service handle, and returns a pointer to it. -This routine returns -.Dv NULL -if it fails, and an error message is logged. -.Fa sendsz -and -.Fa recvsz -are parameters used to specify the size of the buffers. -If they are 0, suitable defaults are chosen. -The file descriptor -.Fa fildes -should be open and bound. -The server is not registered with -.Xr rpcbind 8 . -.Pp -Warning: -since connectionless-based RPC -messages can only hold limited amount of encoded data, -this transport cannot be used for procedures -that take large arguments or return huge results. -.It Fn svc_fd_create -This routine creates a service on top of an open and bound file descriptor, -and returns the handle to it. -Typically, this descriptor is a connected file descriptor for a -connection-oriented transport. -.Fa sendsz -and -.Fa recvsz -indicate sizes for the send and receive buffers. -If they are 0, reasonable defaults are chosen. -This routine returns -.Dv NULL -if it fails, and an error message is logged. -.It Fn svc_raw_create -This routine creates an RPC -service handle and returns a pointer to it. -The transport is really a buffer within the process's -address space, so the corresponding RPC -client should live in the same address space; -(see -.Fn clnt_raw_create -in -.Xr rpc_clnt_create 3 ) . -This routine allows simulation of RPC and acquisition of -RPC overheads (such as round trip times), -without any kernel and networking interference. -This routine returns -.Dv NULL -if it fails, and an error message is logged. -.Pp -Note: -.Fn svc_run -should not be called when the raw interface is being used. -.It Fn svc_tli_create -This routine creates an RPC -server handle, and returns a pointer to it. -.Fa fildes -is the file descriptor on which the service is listening. -If -.Fa fildes -is -.Dv RPC_ANYFD , -it opens a file descriptor on the transport specified by -.Fa netconf . -If the file descriptor is unbound and -.Fa bindaddr -is not -.Dv NULL , -.Fa fildes -is bound to the address specified by -.Fa bindaddr , -otherwise -.Fa fildes -is bound to a default address chosen by the transport. -.Pp -Note: the -.Vt t_bind -structure comes from the TLI/XTI SysV interface, which -.Nx -does not use. -The structure is defined in -.Aq Pa rpc/types.h -for compatibility as: -.Bd -literal -struct t_bind { - struct netbuf addr; /* network address, see rpc(3) */ - unsigned int qlen; /* queue length (for listen(2)) */ -}; -.Ed -.Pp -In the case where the default address is chosen, -the number of outstanding connect requests is set to 8 -for connection-oriented transports. -The user may specify the size of the send and receive buffers -with the parameters -.Fa sendsz -and -.Fa recvsz ; -values of 0 choose suitable defaults. -This routine returns -.Dv NULL -if it fails, -and an error message is logged. -The server is not registered with the -.Xr rpcbind 8 -service. -.It Fn svc_tp_create -.Fn svc_tp_create -creates a server handle for the network -specified by -.Fa netconf , -and registers itself with the rpcbind service. -.Fa dispatch -is called when there is a remote procedure call -for the given -.Fa prognum -and -.Fa versnum ; -this requires calling -.Fn svc_run . -.Fn svc_tp_create -returns the service handle if it succeeds, -otherwise a -.Dv NULL -is returned and an error message is logged. -.It Fn svc_vc_create -This routine creates a connection-oriented RPC -service and returns a pointer to it. -This routine returns -.Dv NULL -if it fails, and an error message is logged. -The users may specify the size of the send and receive buffers -with the parameters -.Fa sendsz -and -.Fa recvsz ;
