List of all members.

Detailed Description

The IConnectionManager interface supports dynamic creation of connection objects given a provider name. Derives from IConnectionManager interface.
Remarks:
In order for dynamic creation to work, each dynamic link library, shared library, or assembly that implements a provider must supply a well-defined entry point function that takes as input a provider name and returns an FdoIConnection instance. The definition of the entry point function is language- and platform-dependent. For this release of FDO, the windows libraries supporting FDO providers will be expected to support the following well-known entry point function, which will create and return an unitialized connection object: IConnection * CreateConnection();
