Getting the size of a buffer Hide the details

<Result> = Length(<Initial buffer>)
<Result>: Integer
Number of bytes in the buffer.
<Initial buffer>: Buffer
Buffer whose size will be calculated.
Linux In UNICODE, each character occupies four memory bytes. Therefore, the size of a buffer containing a UNICODE string corresponds to four times the number of characters actually found in the string in Windows.
