Code cleanup
Description:
Trim trailing whitespace, which is making 'diff'ing the two branches
difficult.
Solution:
Ran this script in each directory:
foreach f (*.[ch] *.cpp)
sed 's/[[:blank:]]*$//' $f > sed.out && mv sed.out $f
end
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest

* This example demonstrates how the data transform features of
|
|
* HDF5 works.
|
|
*
|
|
* (1)
|
|
* The test first writes out data, with no data transform set.
|
|
* Then, the test reads back this data with a data transform applied.
|
|
*
|
|
* (2)
|
|
* Then, the test writes a new set of data, with a data transform set.
|
|
* Then, the test reads this new set of data, without a data set.
|
|
*
|
|
* (3)
|
|
* Lastly, the test reads the previous set of data (that was written out
|
|
* with a data transform) with a data transform set for the read.
|
|
*
|
|
* (4)
|
|
* Get the transform from the property using H5Pget_data_transform.
