* Created: swmr_addrem_writer.c

|
*
|
|
* Purpose: Adds and removes data to a randomly selected subset of the
|
|
* datasets in the SWMR test file.
|
|
*
|
|
* This program is intended to run concurrently with the
|
|
* swmr_reader program. It is also run AFTER a sequential
|
|
* (not concurrent!) invoking of swmr_writer so the writer
|
|
* can dump a bunch of data into the datasets. Otherwise,
|
|
* there wouldn't be much to shrink :)
