-/**
- Convert a Null-terminated Unicode hexadecimal string to a value of type
- UINT64.
-
- This function outputs a value of type UINT64 by interpreting the contents of
- the Unicode string specified by String as a hexadecimal number. The format of
- the input Unicode string String is:
-
- [spaces][zeros][x][hexadecimal digits].
-
- The valid hexadecimal digit character is in the range [0-9], [a-f] and [A-F].
- The prefix "0x" is optional. Both "x" and "X" is allowed in "0x" prefix.
- If "x" appears in the input string, it must be prefixed with at least one 0.
- The function will ignore the pad space, which includes spaces or tab
- characters, before [zeros], [x] or [hexadecimal digit]. The running zero
- before [x] or [hexadecimal digit] will be ignored. Then, the decoding starts
- after [x] or the first valid hexadecimal digit. Then, the function stops at
- the first character that is a not a valid hexadecimal character or NULL,
- whichever one comes first.
-
- If String is NULL, then ASSERT().
- If Data is NULL, then ASSERT().
- If String is not aligned in a 16-bit boundary, then ASSERT().
- If PcdMaximumUnicodeStringLength is not zero, and String contains more than
- PcdMaximumUnicodeStringLength Unicode characters, not including the
- Null-terminator, then ASSERT().
-
- If String has no valid hexadecimal digits in the above format, then 0 is
- stored at the location pointed to by Data.
- If the number represented by String exceeds the range defined by UINT64, then
- MAX_UINT64 is stored at the location pointed to by Data.
-
- If EndPointer is not NULL, a pointer to the character that stopped the scan
- is stored at the location pointed to by EndPointer. If String has no valid
- hexadecimal digits right after the optional pad spaces, the value of String
- is stored at the location pointed to by EndPointer.
-
- @param String Pointer to a Null-terminated Unicode string.
- @param EndPointer Pointer to character that stops scan.
- @param Data Pointer to the converted value.
-
- @retval RETURN_SUCCESS Value is translated from String.
- @retval RETURN_INVALID_PARAMETER If String is NULL.
