How to make sure application stops working when dongle is removed from a machine .

[#1]

After reconnection attempts fails, the client tries to exit the application. The default behavior in Windows will be Pop-up dialog box with update about the error. The application will exit once the dialog box is closed.
In case, you want to change the exit behavior, you can write your own callback under the attribute:

(void)lc_set_attr(lm_job, LM_A_USER_EXITCALL_EX, (LM_A_VAL_TYPE)quit);

The callback can be written as

static int quit(LM_HANDLE* lm_job,char* feat, void* itr)

{

printf("LM_A_USER_EXITCALL_EX is called for %s \n", feat); exit(0);

}
