+/**\r
+ Converts a decimal value to a Null-terminated Unicode string.\r
+ \r
+ Converts the decimal number specified by Value to a Null-terminated Unicode \r
+ string specified by Buffer containing at most Width characters.\r
+ If Width is 0 then a width of MAXIMUM_VALUE_CHARACTERS is assumed.\r
+ The total number of characters placed in Buffer is returned.\r
+ If the conversion contains more than Width characters, then only the first\r
+ Width characters are returned, and the total number of characters \r
+ required to perform the conversion is returned.\r
+ Additional conversion parameters are specified in Flags. \r
+ The Flags bit LEFT_JUSTIFY is always ignored.\r
+ All conversions are left justified in Buffer.\r
+ If Width is 0, PREFIX_ZERO is ignored in Flags.\r
+ If COMMA_TYPE is set in Flags, then PREFIX_ZERO is ignored in Flags, and commas\r
+ are inserted every 3rd digit starting from the right.\r
+ If Value is < 0, then the fist character in Buffer is a '-'.\r
+ If PREFIX_ZERO is set in Flags and PREFIX_ZERO is not being ignored, \r
+ then Buffer is padded with '0' characters so the combination of the optional '-' \r
+ sign character, '0' characters, digit characters for Value, and the Null-terminator\r
+ add up to Width characters.\r
+\r
+ If Buffer is NULL, then ASSERT().\r
+ If unsupported bits are set in Flags, then ASSERT().\r
+ If Width >= MAXIMUM_VALUE_CHARACTERS, then ASSERT()\r
+\r
+ @param Buffer Pointer to the output buffer for the produced Null-terminated\r
+ Unicode string.\r
+ @param Flags The bitmask of flags that specify left justification, zero pad, and commas.\r
+ @param Value The 64-bit signed value to convert to a string.\r
+ @param Width The maximum number of Unicode characters to place in Buffer.\r
+ \r
+ @return Total number of characters required to perform the conversion.\r
