|
|
* Purpose: Create a file with a dataset who's raw data immediately follows
|
|
* its object header, so that when the dataset is unlinked from its parent
|
|
* group, a speculative read of the object header would get the raw data
|
|
* into the metadata accumulator, "polluting" it.
|
|
* To build the test file, this program MUST be compiled and linked with
|
|
* the library on the trunk as of when this file is checked in.
