int svc_create()
svc_create() creates server handles for all the transports belonging to the class nettype .
nettype defines a class of transports which can be used for a particular application. The transports
are tried in left to right order in
NETPATH variable or in top to bottom order in the netconfig data-
base. If nettype is
NULL, it defaults to
netpath.
svc_create() registers itself with the rpcbind service (see rpcbind (1M)). dispatch is called
when there is a remote procedure call for the given prognum and versnum; this requires calling
svc_run() (see svc_run() in rpc_svc_reg (3N)). If svc_create()
succeeds, it returns the
number of server handles it created, otherwise it returns 0 and an error message is logged.
void svc_destroy()
A function macro that destroys the RPC service handle xprt. Destruction usually involves dealloca-
tion of private data structures, including xprt itself. Use of xprt is undefined after calling this rou-
tine.
SVCXPRT *svc_dg_create()
This routine creates a connectionless RPC service handle, and returns a pointer to it. This routine
returns
NULL if it fails, and an error message is logged. sendsz and recvsz are parameters used to
specify the size of the buffers. If they are
0, suitable defaults are chosen. The file descriptor fildes
should be open and bound. The server is not registered with rpcbind(1M).
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.
SVCXPRT *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.
sendsz and recvsz indicate sizes for the send and receive buffers. If they are 0
, reasonable defaults
are chosen. This routine returns
NULL if it fails, and an error message is logged.
SVCXPRT *svc_raw_create(void)
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
clnt_raw_create()
in rpc_clnt_create(3N)). This routine allows simulation
of RPC and acquisition of RPC overheads (such as round trip times), without any kernel and net-
working interference. This routine returns
NULL if it fails, and an error message is logged.
Note:
svc_run() should not be called when the raw interface is being used.
SVCXPRT *svc_tli_create()
This routine creates an RPC server handle, and returns a pointer to it. fildes is the file descriptor
on which the service is listening. If fildes is RPC_ANYFD, it opens a file descriptor on the transport
specified by netconf . If the file descriptor is unbound and bindaddr is non-null fildes is bound to the
address specified by bindaddr, otherwise fildes is bound to a default address chosen by the tran-
sport. 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 sendsz and recvsz ; values of
0 choose suitable defaults. This routine
returns NULL if it fails, and an error message is logged. The server is not registered with the
rpcbind(1M) service.
SVCXPRT *svc_tp_create()
svc_tp_create() creates a server handle for the network specified by netconf, and registers
itself with the rpcbind service. dispatch is called when there is a remote procedure call for the
given prognum and versnum; this requires calling svc_run(). svc_tp_create() returns the
service handle if it succeeds, otherwise a NULL is returned and an error message is logged.
SVCXPRT *svc_vc_create()
This routine creates a connection-oriented RPC service and returns a pointer to it. This routine
returns 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 sendsz and recvsz; values of 0 choose suitable defaults. The
file descriptor fildes should be open and bound. The server is not registered with the rpcbind(1M)
service.
