public function hexToInt64TrueError(input, output, startpos, endpos) result(error)Parse the input string as bits represented by hexadecimal digits to an int64 value.
This function ignores leading and trailing whitespaces.
This function return an int32 value of 0 on successful parse cases or a true error code on unsuccessful parse cases.
Error codes:
0 - none
1 - empty strings
2 - invalid format
3 - value too large for data type
5 - Invalid argument endpos/startpos
