hdf5/tools/h5tools.h
Robb Matzke 96f9f1859b [svn-r2412] Fixed a variety of problems with the new H5ToolsFopen() function. 
1. The `driver' table is initialized only once, making it faster and
     leaking less memory.
  2. The returned driver name is set to the empty string on failure.
  3. Added an argument so the function cannot overwrite the end of the
     drivername return value.
  4. Avoids core dump when assigning driver name to return value if the
     file could not be opened by any driver.
  5. Changed name of function to h5dump_fopen() to follow the naming
     scheme for this source file.
  6. Reindented according to hdf5 code standard.
  7. Added `const' qualifiers to read-only formals.
  8. Removed duplicate forward declaration.

Reindented some parts of these source files that had very odd indentation
(some lines had no indentation while others had 3x what they should).

Fixed calls to H5ToolsFopen() function.

/*
* Fields associated with formatting numeric data. If a datatype matches
* multiple formats based on its size, then the first applicable format
* from this list is used. However, if `raw' is non-zero then dump all
* 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

* data which is longer than one line of output. The default
* value is the current value of the `pre' field
* described above.

* 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
