[svn-r537] Changes since 19980722
---------------------- ./src/H5A.c ./src/H5Apublic.h ./test/tattr.c Switched the order of the second and third argument of H5Aget_name() to make it consistent with other functions that take buffers and buffer sizes. ./src/H5G.c ./src/H5Gpublic.h ./src/H5Gprivate.h The H5Gget_comment() function returns the size of the comment including the null terminator. If the object has no comment then zero is returned. If an error occurs then a negative value is returned. ./MANIFEST ./tools/Makefile.in ./tools/h5tools.h [NEW] ./tools/h5dump.c [NEW] Created a library for printing values of datasets in a way that looks nice. It's not done yet, but I needed it for debugging the contents of files from Jim Reus. ./tools/h5ls.c Added the `-d' and `--dump' options which cause the contents of a dataset to be printed. Added `-w N' and `--width=N' options to control how wide the raw data output should be. If you want single-column output then say `-w1'. Printing dataset values can now handle datasets of any integer or floating point atomic type. As a special case, integers which are one byte wide are treated a character strings for now. Sample output: $ h5ls --dump --width=60 banana.hdf ARCHIVE 0:0:0:744 Dataset {52/Inf} Data: (0) "U struct complex { double R; double I; };\012V" (43) " double;\012" U 0:0:0:2500 Dataset {256/512} Data: printing of compound data types is not implemented yet V 0:0:0:3928 Dataset {256/512} Data: (0) 0, 0.015625, 0.03125, 0.046875, 0.0625, (5) 0.078125, 0.09375, 0.109375, 0.125, 0.140625, (10) 0.15625, 0.171875, 0.1875, 0.203125, 0.21875, (15) 0.234375, 0.25, 0.265625, 0.28125, 0.296875, ...
