Description

Create will initialize a TGUID from byte data. The byte-data can come in different forms

Data: can be a plain buffer. The GUID Data will be read from the buffer (SizeOf(TGUID) bytes), according to the BigEndian argument.
Data: can be an array of bytes. SizeOf(TGUID) bytes will be read from the array, starting at index StartIndex (default 0). The GUID Data will be read according to the BigEndian argument.
S: can be a string containing a string representation of the GUID, which is converted using StringToGUID.
A,B,C,D (optionally E,F,G,H,I,J,K): where the arguments are simply the various components of the GUID.
