data structure.
svc_control
()SVCGET_VERSQUIET
RPC_PROGVERSMISMATCH
error will
normally be returned. info should be a pointer
to an integer. Upon successful completion of the
SVCGET_VERSQUIET
request,
*info contains an integer which describes the
server's current behavior: 0 indicates normal server behavior (that
is, an RPC_PROGVERSMISMATCH
error will be
returned); 1 indicates that the out of range request will be silently
ignored.SVCSET_VERSQUIET
RPC_PROGVERSMISMATCH
error will
normally be returned. It is sometimes desirable to change this
behavior. info should be a pointer to an integer
which is either 0 (indicating normal server behavior - an
RPC_PROGVERSMISMATCH
error will be returned),
or 1 (indicating that the out of range request should be silently
ignored).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 database. If nettype
is NULL
, it defaults to
netpath
.
svc_create
() registers itself with the
rpcbind service (see
rpcbind(8)).
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(3)).
If svc_create
() succeeds, it returns the number
of server handles it created, otherwise it returns 0 and an error
message is logged.
svc_destroy
()svc_dg_create
()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(8).
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.svc_fd_create
()NULL
if it fails,
and an error message is logged.svc_raw_create
()clnt_raw_create
() in
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 NULL
if it
fails, and an error message is logged. Note:
svc_run
() should not be called when the raw
interface is being used.svc_tli_create
()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 transport.
Note: the t_bind structure comes from
the TLI/XTI SysV interface, which NetBSD does
not use. The structure is defined in
<rpc/types.h>
for
compatibility as:
struct t_bind { struct netbuf addr; /* network address, see rpc(3) */ unsigned int qlen; /* queue length (for listen(2)) */ };
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(8) service.
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.svc_vc_create
()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(8) service.May 3, 1993 | NetBSD 9.2 |
