Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-)
Description:
Generally speaking, this is the "signed->unsigned" change to selections.
However, in the process of merging code back, things got stickier and stickier
until I ended up doing a big "sync the two branches up" operation. So... I
brought back all the "infrastructure" fixes from the development branch to the
release branch (which I think were actually making some improvement in
performance) as well as fixed several bugs which had been fixed in one branch,
but not the other.
I've also tagged the repository before making this checkin with the label
"before_signed_unsigned_changes".
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel & fphdf5
FreeBSD 4.10 (sleipnir) w/threadsafe
FreeBSD 4.10 (sleipnir) w/backward compatibility
Solaris 2.7 (arabica) w/"purify options"
Solaris 2.8 (sol) w/FORTRAN & C++
AIX 5.x (copper) w/parallel & FORTRAN
IRIX64 6.5 (modi4) w/FORTRAN
Linux 2.4 (heping) w/FORTRAN & C++

! This program creates two files, copy1.h5, and copy2.h5.
|
|
! In copy1.h5, it creates a 3x4 dataset called 'Copy1',
|
|
! and write 0's to this dataset.
|
|
! In copy2.h5, it create a 3x4 dataset called 'Copy2',
|
|
! and write 1's to this dataset.
|
|
! It closes both files, reopens both files, selects two
|
|
! points in copy1.h5 and writes values to them. Then it
|
|
! uses an H5Scopy to write the same selection to copy2.h5.
|
|
! Program reopens the files, and reads and prints the contents of
|
|
! the two datasets.
