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++

/* PROGRAM: h5_copy.c */
|
|
/* PURPOSE: Shows how to use the H5SCOPY function. */
|
|
/* DESCRIPTION: */
|
|
/* 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 */
|
|
/* does an H5Scopy from the first file to the second, and */
|
|
/* writes the values to copy2.h5. It then closes the */
|
|
/* files, reopens them, and prints the contents of the */
|
|
/* two datasets. */
