Return RETURN_INVALID_PARAMETER when: 1). The input Buffer is NULL. 2). The input BufferSize is greater than (PcdMaximumUnicodeStringLength * sizeof (CHAR16) + 1) for UnicodeValueToStringS or greater than PcdMaximumAsciiStringLength for AsciiValueToStringS. 3). The input Flags is not set properly. 4). The input Width is not smaller than MAXIMUM_VALUE_CHARACTERS. Return RETURN_BUFFER_TOO_SMALL when: 1). The input BufferSize cannot hold the converted value.
