ODABAClient :: OpenDataSource - Open data source

The data source to be opened must be defined in the ini-file for the application or in the data catalog. When the data source has been opened successfully the function returns a pointer to a database object handle. The application is responsible to destroy the database object handle, when it is not being used anymore by calling delete or the CloseDataSource() function.

The access mode (accept) can be passed to reduce the access rights defined in the data source (typically from write to read). You cannot increase the access rights (e.g. from read to write).
