[svn-r12437] Purpose:
new feature. h5dump output of binary data Description: a new switch -b FILE_NAME that dumps the contents of memory data to file FILE_NAME in binary form new program binread.c that reads the contents of this file and outputs it to stdout added a test for the h5dump shell script that does a run of -b the binread.c program reads the data used in this run, usage is ./binread FILE_NAME Solution: Platforms tested: linux solaris AIX Misc. update:
