[svn-r15] ./src/H5AC.c
./src/H5ACprivate.h
./src/H5ACproto.h
./src/H5Bproto.h
./src/H5Gproto.h
./src/H5Hproto.h
./src/H5MFprivate.h
./src/H5MFproto.h
./src/H5MM.c
./src/H5MMprivate.h
./src/H5MMproto.h
Changed my e-mail address.
./src/H5O.c NEW
./src/H5Onull.c NEW
./src/H5Ocont. NEW
./src/H5Ostab.c NEW
New functions for dealing with object headers. The H5O.c is
the generic stuff, and each particular message has a source
file for the specific stuff.
Use ./src/H5Ostab.c as a model for implementing other messages.
./src/Makefile
./src/test/Makefile
Added new files
./src/debug.c
Added debugging calls for object headers.
./src/H5B.c
./src/H5Bprivate.h
./src/H5Gnode.c
./src/H5MF.c
Changed my e-mail address.
Improved error handling.
./src/H5Eprivate.h
./src/H5Eproto.h
Added more error symbols
./src/H5F.c
Changed my e-mail address.
Used macros for sizeof offsets and lengths.
Added the interface initialization function to
H5F_block_read() and H5F_block_write().
Updated H5F_debug()
./src/H5Fprivate.h
Got rid of H5F_symbol_table_size(). Use H5G_SIZEOF_ENTRY()
instead.
Reformatted H5F_decode_offset() for readability.
./src/H5G.c
Changed my e-mail address.
Improved error handling.
Replaced not_implemented_yet__*() with real functions from
H5O.
./src/H5Gprivate.h
Changed `symtab' to `stab' to be consistent with other stuff.
./src/H5H.c
./src/H5Hprivate.h
Changed my e-mail address.
Improved error handling.
Added an extra argument to H5H_new() to indicate whether you
want a global heap or a local heap.
./src/hdf5gen.h
Added NELMTS()
Fixed FUNC_ENTER()
Rewrote FUNC_LEAVE() in terms of HRETURN().
./src/hdf5meta.h
Added `const' to the decode macros.
./src/hdf5pabl.h
Added PABLO_SAVE()
./test/testhdf5.c
./test/testhdf5.h
Added calls for object header testing.
./test/theap.c
Turned off some output.
