hdf5/tools/lib/h5tools.h
Pedro Vicente Nunes 78ca05e040 [svn-r8644] Purpose: h5dump new features 
Description:

added the code for print strings with new line and display the path of references (new source files h5tools_ref.c and .h )
added a test suite in testh5dump.sh.in for
( note : to create testh5dump.sh , one must redo ./configure; this detects the availability of filters
and generates  testh5dump.sh accordingly)
1) storage layout
2) fill value
3) print reference with path
4) print strings with new lines
5) filters

Solution:

Platforms tested:
linux
solaris
AIX

* multiple formats based on its size, then the first applicable format

* data in hexadecimal format without translating from what appears on
* disk.
*
* raw: If set then print all data as hexadecimal without
* performing any conversion from disk.
*
* fmt_raw: The printf() format for each byte of raw data. The
* default is `%02x'.
*
* fmt_int: The printf() format to use when rendering data which is
* typed `int'. The default is `%d'.
*
* fmt_uint: The printf() format to use when rendering data which is
* typed `unsigned'. The default is `%u'.
*
* fmt_schar: The printf() format to use when rendering data which is
* typed `signed char'. The default is `%d'. This format is
* used ony if the `ascii' field is zero.
*
* fmt_uchar: The printf() format to use when rendering data which is
* typed `unsigned char'. The default is `%u'. This format
* is used only if the `ascii' field is zero.
*
* fmt_short: The printf() format to use when rendering data which is
* typed `short'. The default is `%d'.
*
* fmt_ushort: The printf() format to use when rendering data which is
* typed `unsigned short'. The default is `%u'.
*
* fmt_long: The printf() format to use when rendering data which is
* typed `long'. The default is `%ld'.
*
* fmt_ulong: The printf() format to use when rendering data which is
* typed `unsigned long'. The default is `%lu'.
*
* fmt_llong: The printf() format to use when rendering data which is
* typed `long long'. The default depends on what printf()
* format is available to print this datatype.
*
* fmt_ullong: The printf() format to use when rendering data which is
* typed `unsigned long long'. The default depends on what
* printf() format is available to print this datatype.
*
* fmt_double: The printf() format to use when rendering data which is
* typed `double'. The default is `%g'.
*
* fmt_float: The printf() format to use when rendering data which is
* typed `float'. The default is `%g'.
*
* ascii: If set then print 1-byte integer values as an ASCII
* character (no quotes). If the character is one of the
* standard C escapes then print the escaped version. If
* the character is unprintable then print a 3-digit octal
* escape. If `ascii' is zero then then 1-byte integers are
* printed as numeric values. The default is zero.
*
* str_locale: Determines how strings are printed. If zero then strings
* are printed like in C except. If set to ESCAPE_HTML then
* strings are printed using HTML encoding where each
* character not in the class [a-zA-Z0-9] is substituted
* with `%XX' where `X' is a hexadecimal digit.
*
* str_repeat: If set to non-zero then any character value repeated N
* or more times is printed as 'C'*N
*
* Numeric data is also subject to the formats for individual elements.

* pre: Each line of output contains an optional prefix area
* before the data. This area can contain the index for the
* first datum (represented by `%s') as well as other
* constant text. The default value is `%s'.
*
* 1st: This is the format to print at the beginning of the first
* line of output. The default value is the current value of
* `pre' described above.
*
* cont: This is the format to print at the beginning of each line
* which was continued because the line was split onto
* multiple lines. This often happens with compound
* data which is longer than one line of output. The default
* value is the current value of the `pre' field
* described above.

* suf: This character string will be appended to each line of
* output. It should not contain line feeds. The default
* is the empty string.
*
* sep: A character string to be printed after every line feed
* defaulting to the empty string. It should end with a
* line feed.
*
* multi_new: Indicates the algorithm to use when data elements tend to
* occupy more than one line of output. The possible values
* are (zero is the default):
*
* 0: No consideration. Each new element is printed
* beginning where the previous element ended.
*
* 1: Print the current element beginning where the
* previous element left off. But if that would result
* in the element occupying more than one line and it
* would only occupy one line if it started at the
* beginning of a line, then it is printed at the
* beginning of the next line.
*
* multi_new: If an element is continued onto additional lines then
* should the following element begin on the next line? The
* default is to start the next element on the same line
* unless it wouldn't fit.
*
* indentlevel: a string that shows how far to indent if extra spacing
