/******************************************************************************
 * Variant-Formats {OLEAUT32}
 *
 * NOTES
 *  When formatting a variant a variety of format strings may be used to generate
 *  different kinds of formatted output. A format string consists of either a named
 *  format, or a user-defined format.
 *
 *  The following named formats are defined:
 *| Name           Description
 *| ----           -----------
 *| General Date   Display Date, and time for non-integer values
 *| Short Date     Short date format as defined by locale settings
 *| Medium Date    Medium date format as defined by locale settings
 *| Long Date      Long date format as defined by locale settings
 *| Short Time     Short Time format as defined by locale settings
 *| Medium Time    Medium time format as defined by locale settings
 *| Long Time      Long time format as defined by locale settings
 *| True/False     Localised text of "True" or "False"
 *| Yes/No         Localised text of "Yes" or "No"
 *| On/Off         Localised text of "On" or "Off"
86
 *| General Number No thousands separator. No decimal points for integers
87 88
 *| Currency       General currency format using localised characters
 *| Fixed          At least one whole and two fractional digits
89 90
 *| Standard       Same as 'Fixed', but including decimal separators
 *| Percent        Multiply by 100 and display a trailing '%' character
91 92 93 94 95 96
 *| Scientific     Display with exponent
 *
 *  User-defined formats consist of a combination of tokens and literal
 *  characters. Literal characters are copied unmodified to the formatted
 *  output at the position they occupy in the format string. Any character
 *  that is not recognised as a token is treated as a literal. A literal can
97
 *  also be specified by preceding it with a backslash character
98 99 100
 *  (e.g. "\L\i\t\e\r\a\l") or enclosing it in double quotes.
 *
 *  A user-defined format can have up to 4 sections, depending on the type of
101
 *  format. The following table lists sections and their meaning:
102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154
 *| Format Type  Sections Meaning
 *| -----------  -------- -------
 *| Number       1        Use the same format for all numbers
 *| Number       2        Use format 1 for positive and 2 for negative numbers
 *| Number       3        Use format 1 for positive, 2 for zero, and 3
 *|                       for negative numbers.
 *| Number       4        Use format 1 for positive, 2 for zero, 3 for
 *|                       negative, and 4 for null numbers.
 *| String       1        Use the same format for all strings
 *| String       2        Use format 2 for null and empty strings, otherwise
 *|                       use format 1.
 *| Date         1        Use the same format for all dates
 *
 *  The formatting tokens fall into several categories depending on the type
 *  of formatted output. For more information on each type, see
 *  VarFormat-Dates(), VarFormat-Strings() and VarFormat-Numbers().
 *
 *  SEE ALSO
 *  VarTokenizeFormatString(), VarFormatFromTokens(), VarFormat(),
 *  VarFormatDateTime(), VarFormatNumber(), VarFormatCurrency().
 */

/******************************************************************************
 * VarFormat-Strings {OLEAUT32}
 *
 * NOTES
 *  When formatting a variant as a string, it is first converted to a VT_BSTR.
 *  The user-format string defines which characters are copied into which
 *  positions in the output string. Literals may be inserted in the format
 *  string. When creating the formatted string, excess characters in the string
 *  (those not consumed by a token) are appended to the end of the output. If
 *  there are more tokens than characters in the string to format, spaces will
 *  be inserted at the start of the string if the '@' token was used.
 *
 *  By default strings are converted to lowercase, or uppercase if the '>' token
 *  is encountered. This applies to the whole string: it is not possible to
 *  generate a mixed-case output string.
 *
 *  In user-defined string formats, the following tokens are recognised:
 *| Token  Description
 *| -----  -----------
 *| '@'    Copy a char from the source, or a space if no chars are left.
 *| '&'    Copy a char from the source, or write nothing if no chars are left.
 *| '<'    Output the whole string as lower-case (the default).
 *| '>'    Output the whole string as upper-case.
 *| '!'    MSDN indicates that this character should cause right-to-left
 *|        copying, however tests show that it is tokenised but not processed.

 *              VarTokenizeFormatString [OLEAUT32.140]
 *
 * Convert a format string into tokenised form.
 *
 * PARAMS
 *  lpszFormat [I] Format string to tokenise
 *  rgbTok     [O] Destination for tokenised format
 *  cbTok      [I] Size of rgbTok in bytes
 *  nFirstDay  [I] First day of the week (1-7, or 0 for current system default)
 *  nFirstWeek [I] How to treat the first week (see notes)
 *  lcid       [I] Locale Id of the format string
 *  pcbActual  [O] If non-NULL, filled with the first token generated
 *
 * RETURNS
 *  Success: S_OK. rgbTok contains the tokenised format.
 *  Failure: E_INVALIDARG, if any argument is invalid.
 *           TYPE_E_BUFFERTOOSMALL, if rgbTok is not large enough.
 *
 * NOTES
 * Valid values for the nFirstWeek parameter are:
 *| Value  Meaning
 *| -----  -------
 *|   0    Use the current system default
 *|   1    The first week is that containing Jan 1
 *|   2    Four or more days of the first week are in the current year
