[svn-r949] Changes since 19981124
----------------------
./src/H5T.c
Fixed a typo in the registration of the `unsigned char' to
`unsigned long long' type conversion that caused it to not be
registered, falling back to software whenever that conversion
path was taken.
./MANIFEST
./test/Makefile.in
./test/testhdf5.c
./test/testhdf5.h
./test/theap.c [REMOVED]
./test/lheap.c [NEW]
./test/tohdr.c [REMOVED]
./test/ohdr.c [NEW]
./test/tstab.c [REMOVED]
./test/stab.c [NEW]
Removed the `t' from the front of these names and made each
test a stand-alone program following the format of most of the
other tests.
./test/big.c
Uses libh5test.a but always sets the low-level driver to 1GB
file family.
The `#if' near the top to set the data space to 8GB has been
simplified now that `long_long' is always defined and the
error message is improved when `long_long' isn't wide enough.
Cleanup code was added to the error handling.
./test/gheap.c
./test/istore.c
Uses libh5test.a. Added error cleanup code.
./test/dtypes.c
./test/h5test.c
Added 68 new tests that check hardware and software
conversions between `long long' and `unsigned long long' and
the other integer types. The tests only run on machines where
sizeof(long_long)!=sizeof(long). We test a total of 180
different integer conversions, half in hardware and half in
software.
Cut down the number of times each test is run from 5 to 1 so
it doesn't take so long. If you want to run more times
there's a constant that can be changed at the top of the file.
./test/extend.c
Removed unused variable.
./test/h5test.c
./test/h5test.h
./test/external.c
./test/fillval.c
The h5_cleanup() returns true/false so it can be used in an `if'
statement to clean up additional files.
./doc/html/Environment.html
Indented. Added HDF5_PREFIX and HDF5_DRIVER descriptions.
./src/H5P.c
Changed the trace type for the second argument from `Iu' to
`x' since it's an output parameter.
./INSTALL
Added a warning that the GNU zlib that comes with the latest
version of HDF4 is too old to use with HDF5 and must be
renamed so configure doesn't see it when `--enable-hdf4' is
used.
