(2) When SVR_AUTH has been specified
Each of the client-stub functions has a different API from the corresponding actual server function
and the server ID and server version information are added as parameters. RPCGEN outputs the
client-stub functions themselves to <config file>_clnt.c and the prototype declarations to <config
file>_clnt.h.
The name of each client-stub function takes the form rpcclnt_<server name>_<server function
name>. <Server name> refers to the server name defined with SVR_NAME and <server function
name> refers to server function names defined between the braces {} of RPC_FUNC.
The first and second parameters of the client-stub functions are the server ID and server version,
respectively. The names of the parameters are fixed to __ulID and __ulVers. The third and
subsequent parameters are the first and subsequent parameters of the actual server function and
their names are those defined in RPC_FUNC.
Example:
Contents of a config file
SVR_NAME{ EXAMPLE };
SVR_ID{ 1 };
SVR_VERSION{ 2 };
SVR_AUTH;
RPC_FUNC{
int ret = func1([IN DFLT]int par1, [IN DFLT]int par2);
func2([OUT PTR]struct ST *ptr);
};
Specification of a client-stub function
int rpcclnt_EXAMPLE_func1(UINT32 __ulID, UINT32 __ulVers, int par1, int
par2);
void rpcclnt_EXAMPLE_func2(UINT32 __ulID, UINT32 __ulVers, struct ST
*ptr);
