+/**\r
+ Internal function that converts a decimal value to a Null-terminated string.\r
+\r
+ Converts the decimal number specified by Value to a Null-terminated string\r
+ specified by Buffer containing at most Width characters. If Width is 0 then a\r
+ width of MAXIMUM_VALUE_CHARACTERS is assumed. If the conversion contains more\r
+ than Width characters, then only the first Width characters are placed in\r
+ Buffer. 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\r
+ commas 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\r
+ Null-terminator add up to Width characters.\r
+\r
+ If an error would be returned, the function will ASSERT().\r
+\r
+ @param Buffer The pointer to the output buffer for the produced\r
+ Null-terminated string.\r
+ @param BufferSize The size of Buffer in bytes, including the\r
+ Null-terminator.\r
+ @param Flags The bitmask of flags that specify left justification,\r
+ zero pad, and commas.\r
+ @param Value The 64-bit signed value to convert to a string.\r
+ @param Width The maximum number of characters to place in Buffer,\r
+ not including the Null-terminator.\r
+ @param Increment The character increment in Buffer.\r
+\r
+ @retval RETURN_SUCCESS The decimal value is converted.\r
+ @retval RETURN_BUFFER_TOO_SMALL If BufferSize cannot hold the converted\r
+ value.\r
+ @retval RETURN_INVALID_PARAMETER If Buffer is NULL.\r
+ If Increment is 1 and\r
+ PcdMaximumAsciiStringLength is not zero,\r
+ BufferSize is greater than\r
+ PcdMaximumAsciiStringLength.\r
+ If Increment is not 1 and\r
+ PcdMaximumUnicodeStringLength is not zero,\r
+ BufferSize is greater than\r
+ (PcdMaximumUnicodeStringLength *\r
+ sizeof (CHAR16) + 1).\r
+ If unsupported bits are set in Flags.\r
+ If both COMMA_TYPE and RADIX_HEX are set in\r
+ Flags.\r
+ If Width >= MAXIMUM_VALUE_CHARACTERS.\r
