ICcService::GetCurrentState (Compact 2013)
3/26/2014
Deprecated.
This method returns the program state of the service.
Syntax
HRESULT GetCurrentState (
DWORD* pdwCurrentState
);
Parameters
pdwCurrentState
[out, retval] Current state of the service.The first four bits of the service state are reserved for pre-defined service states. Service states 5 and 6 are not used.
For caching purposes, the SERVICE_LOCKED state determines if the lock count on a service is a positive number.
If the lock count of the service is greater than 0, Core Connectivity requires the service to set the lock count bit, the fourth bit, to 0x1xxx.
If the lock count is not a positive number, the service should clear the service state bit; that is, it should set the bit to 0x0xxx.
The SERVICE_LOCKED state is combined with other services in an OR relationship.
Core Connectivity requires custom service providers to set the service state to a pre-defined value at different points during the service lifetime. Custom services can add additional service states.
The following table describes valid service states.
