* Thursday, July 23, 1998

* Modifications:
* Robb Matzke, 1999-04-26
* Made this function safe from overflow problems by allowing it
* to reallocate the output string.
*
* Robb Matzke, 1999-06-04
* Added support for object references. The new `container'
* argument is the dataset where the reference came from.
*
* Robb Matzke, 1999-06-07
* Added support for printing raw data. If info->raw is non-zero
* then data is printed in hexadecimal format.
*
* Robb Matzke, 2003-01-10
* Binary output format is dd:dd:... instead of 0xdddd... so it
* doesn't look like a hexadecimal integer, and thus users will
* be less likely to complain that HDF5 didn't properly byte
* swap their data during type conversion.
*
* Robb Matzke, LLNL, 2003-06-05
* If TYPE is a variable length string then the pointer to
* the value to pring (VP) is a pointer to a `char*'.
*
* PVN, 28 March 2006
* added H5T_NATIVE_LDOUBLE case
*
* Vailin Choi; August 2010
* Modified to handle printing of selected compound fields for h5watch.
*
* Raymond Lu, 2011-09-01
* CLANG compiler complained about the line (about 800):
* tempint = (tempint >> packed_data_offset) & packed_data_mask;
* The right shift may cause undefined behavior if PACKED_DATA_OFFSET is
* 32-bit or more. For every kind of native integers, I changed the code
* to make it zero if PACKED_DATA_OFFSET is greater than or equal to the
* size of integer.
