NAME
rpc_server_use_protseq - Tells the RPC runtime to use the specified
protocol sequence for receiving remote
procedure calls
Used by server applications.
SYNOPSIS
#include <dce/rpc.h>
void rpc_server_use_protseq( unsigned_char_t *protseq,
unsigned32 max_call_requests,
unsigned32 *status );
PARAMETERS
Input
protseq
Specifies a string identifier for the protocol sequence to
register with the RPC runtime. (For a list of string identifiers,
see the table of valid protocol sequences in the rpc_intro(3rpc)
reference page.)
max_call_requests
Specifies the maximum number of concurrent remote procedure call
requests that the server can accept.
The RPC runtime guarantees that the server can accept at least
this number of concurrent call requests. The actual number of
these requests can be greater than the value of max_call_requests
and can vary for each protocol sequence.
Use the value rpc_c_protseq_max_reqs_default to specify the
default parameter value.
Note that in this version of DCE RPC, any number you specify is
replaced by the default value.
Also, rpc_server_listen() limits (according to its max_calls_exec
parameter) the amount of concurrent remote procedure call
execution. See the rpc_server_listen reference page for more
information.
Output
status
Returns the status code from this routine. This status code
indicates whether the routine completed successfully or, if not,
why not. The possible status codes and their meanings are as
follows:
rpc_s_ok Success.
rpc_s_cant_create_socket
Cannot create socket.
rpc_s_invalid_rpc_protseq
Invalid protocol sequence.
rpc_s_max_descs_exceeded
Exceeded maximum number of network descriptors.
rpc_s_protseq_not_supported
Protocol sequence not supported on this host.
DESCRIPTION
The rpc_server_use_protseq() routine registers a single protocol
sequence with the RPC runtime. A server must register at least one
protocol sequence with the RPC runtime to receive remote procedure
call requests. A server can call this routine multiple times to
register additional protocol sequences.
For each protocol sequence registered by a server, the RPC runtime
creates one or more binding handles. Each binding handle contains a
dynamic endpoint that the RPC runtime and operating system generated.
The max_call_requests parameter allows you to specify the maximum
number of concurrent remote procedure call requests the server
handles.
A server calls rpc_server_use_all_protseqs() to register all protocol
sequences.
The explanation of the rpc_server_use_all_protseqs() routine contains
a list of the routines a server typically calls after calling this
routine. For an explanation of how a server can establish a
client/server relationship without using the local endpoint map or
the name service database, see the information on string bindings in
the rpc_intro reference page.
RETURN VALUES
No value is returned.
