Re: C API: Query regarding Speech Dispatcher Callbacks and State Management

[Day Garwood]

Hi Samuel,

Thank you for your prompt response.

I appreciate your suggestion regarding the use of client_id through 
spd_get_client_id.

The challenge I'm facing is that to retrieve the client ID, I'd need 
access to the connection. This connection information, along with other 
data, is part of the state/I'm trying to access.

To provide some context, here's a brief sample of how my code is 
structured right now (error checks are omitted for brevity):


struct my_state

{

spd_connection* connection;

/* Other members here */

};

void init(struct my_state* state)

{

state->connection=spd_connect("myapp", "myclient", NULL, SPD_MODE_THREADED);

/* set callbacks and activate notifications here. */

}


void _vb_spd_callback(int msg, int client, SPDNotificationType state)

{

/* need access to struct my_state* state passed to init and other 
functions here. */

}


Is there another method or mechanism I might be missing to retrieve this?
Thank you for your guidance and understanding.

Best,

Day.
