ICcSvcHost (Windows CE 5.0)
This interface provides methods and properties that implement the Core Connectivity Service Host framework.
The Service Host acts as a broker component between client applications and Core Connectivity services such as the following:
- Kernel Download
- Kernel Transport
- Application Download
- Application Transport
- Custom services
The Core Connectivity Service Host is a COM server that enables the creation of services on a per-user basis.
When a client application requests a Core Connectivity service object, such as a Kernel Transport, Service Host caches a copy of the service. In addition, the Service Host manages the lifetime of the service, caching it until the client calls ICcSvcHost::Unlock.
