Section 8 Application Interface

8.1 Client-Stub Functions Generated by RPCGEN

The client-stub functions are called by the client application.

This section gives the specifications for the client-stub functions generated by RPCGEN. The

client-stub functions must be called in accord with the definitions in these specifications. If

CLNTSTUB is used to prevent creation of client-stub functions, the user must implement client-

stub functions in accord with the specifications.

For details on SVR_AUTH, refer to section 5.5.8, SVR_AUTH.

(1) When SVR_AUTH has not been specified

Each of the client-stub functions has the same API as the actual server function. RPCGEN outputs

the client-stub functions themselves to <config file>_clnt.c but does not output prototype

declarations. Prepare a header file with the required prototype declarations and specify this header

file in the definition of CLNT_INCFILE or GLOBAL_INCFILE.

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 func1(int par1, int par2);

void func2(struct ST *ptr);
