Purpose
Enter an infinite event loop to process SPD events. The function never returns unless there is an error.
Syntax
#using Spo.SPDlib SPD_errorType SPDMainLoop (void);
Description
This function enters an infinite event loop and processes all SPD events in the event queue.
The function allows a client program to simulate single-thread processing of SPD events. It is “simulated” because all event callbacks behind the scene are still handled multi-thread because of the .NET architecture.
Return Value
The return value indicates whether an error occurred, as follows.
| Return | Indication |
| SPD_normal | No error |
| SPD_notInitialized | SPDInitClient not called previously |
| SPD_errException | A .NET runtime exception occurs |
