My pleasure. Nevertheless it isn't being incorrect at all. It is just 
the doc about the human readable format and is irrelevant to the binary 
representation.

It is because Microsoft's own version is defined like that and we 
shouldn't create the incompatibility.

[Mingw-w64-public] GUID definition in guiddef.h

2017-04-28 Thread Vincent Torri 
Hello

in guiddef.h, a GUID is a struct organized as : 4 bytes, 2 bytes 2
bytes and 8 times 1 byte

but according to
https://msdn.microsoft.com/en-us/library/dd354925.aspx at the bottom :

"The correct format of the GUID string is
{CDEF7890-ABCD-1234-ABCD-1234567890AB} where 0-9, A-F symbolizes
hexadecimal digits. "

that is, the GUID structure should be organized as : 4 bytes, 2 bytes
2 bytes 2 bytes and 6 times 1 byte

is it normal that the GUID structure does not follow the MSDN doc ?

Vincent
