QM translation of C++

[ldarrambide]

If the order is not important, then also don't need special packing. I thought the type is used with a dll function.

yes, i missed that and now i understand why pragma is used, it's indeed a dll function in bladeenc.dll

So order IS important as the call of the procedure must match the headers one.....

------------------------------------------------------------------
playing with sizeof, using pragma it's 23, 24 without it.

so this way is explicit packing (you say what variable to pack)

type ____BE_CONFIG11 dwSampleRate !byMode [+1]@wBitrate bPrivate bCRC bCopyright bOriginal

and this one is implicit or automatic, the argument seems to do it automatically

type ____BE_CONFIG11 dwSampleRate !byMode @wBitrate bPrivate bCRC bCopyright bOriginal [pack1]

Is this statement correct?


but i wonder why so much hassle to gain one byte meory, and seems from my readings that it's less perfomant than odd numbers of bytes.


2.

In QM, nonstandard member offsets must be explicitly specified. Including union members. Like in C#. In C/C++ for it are used keyword union and directive #pragma pack.

type __BE_CONFIG1 ____BE_CONFIG11'mp3 []____BE_CONFIG12'LHV1 []____BE_CONFIG13'aac

the empty brackets do mean to use previous packing method then, correct? but they are not the same size....
or is it just a convention for QM to work correctly?

3. ok, just translation of type to QM which own less types than C...i put them on a paper for further reference
