Preferred Place to Start Thread in Photon App

Dear All,

To start a thread in a Photon app I specified an initialization function in PhAB and duplicated all of the code in main() that occured after the initialization function call within the init function. (ugly)

Now I can generate code in PhAB without overwriting calls which should occur in main(). I think the duplication is ugly, does anyone have any suggestions?

Thanks.


int
main ( int argc, char *argv[] )

{

Ap.Ap_winstate = 0;

/* AppBuilder Initialization */
ApInitialize( argc, argv, &AbContext );

initialize_vvmcontrol( argc, argv );

/* Display main window */
ApLinkWindow( NULL, &AbApplLinks[0], NULL );

/* Loop until user quits application */
PtMainLoop( );
PtExit( 0 );

return 0;
}


int
initialize_vvmcontrol( int argc, char* argv[] );
{
/* Display main window */
ApLinkWindow( NULL, &AbApplLinks[0], NULL );

/* start thread here */

/* Loop until user quits application */
PtMainLoop( );
PtExit( 0 );

return 0;
}

I agree it is ugly, but how does it start a thread?

I’m not sure what exactly you’re trying to do, but if you’re just trying
to start a thread, I’d recommend calling pthread_create(). Also, you
might want to check out PtEnter() and PtLeave() in the docs.

Thanks for the tips. I am wondering where the best place to call
pthread_create() would be in a Photon app for a thread that needs to run until app completion.

The initialization function would be my first choice.
