Syntax for C++ action

unsigned int 
action(const char *res_name, const char *action_token,
    void  **attr_val, char **args, char *action_output);

The parameters passed to the C++ action entry point are described as follows using the example that the user fires

$> hares -action res1 myaction...

Use the VCSAgValidateAndSetEntryPoint() API to register the name of the function that implements the action entry-point for the agent.

For example:

extern "C"
unsigned int res_action (const char *res_name, const char
    *token,void **attr_val, char **args, char
    *action_output)
    {
const int output_buffer_size = 2048;
    //
    // checks on the attr_val entry point arg list
    // perform an action based on the action token passed in

if (!strcmp(token, "token1")) {
    //
    // Perform action corresponding to token1
    //
} else if (!strcmp(token, "token2") {
    //
    // Perform action corresponding to token2
    //
}
:
:
:
} else {
    //
    // a token for which no action is implemented yet
    //
VCSAgSnprintf(action_output, output_buffer_size, "No implementation
provided for token(%s)", token);
}
    //
    // Any other checks to be done
    //
    //
    // return value should indicate whether the ep succeeded or
    // not:
    // return 0 on success
    // any other value on failure
    //
if (success) {
return 0;
}
else {
return 1;
}
}
