Is a structure containing an incomplete array as its last element (per
paragraph 2 of section 6.7.2.1 of ISO/IEC 9899:1999 (E)) itself an
incomplete type? That appears to be indicated by paragraph 22 of
section 6.2.5. If so, that seems to make it difficult to allocate such
structures, because sizeof() is not allowed on incomplete types...

I have created a structure with five fields. I then create an array of this
type of structure and place the structure into an array element. Say index
one. I want to assign a value to field3 of the structure inside the array.
When I try this, an error about late assignment appears. Is it possible to
assign a value to a structure field...

If I have a structure like;
Public Structure myStructureDef
Public b() as Byte

End Structure
If I pass this structure, will the values in the array b be stored on the
stack or will just a pointer to the array be stored on the stack? I am
trying to decide whether to use Structures or Pointers. I know that M'soft

Hi Willy,
Thank you very much for your work.
C++ code doesnot make any serialization.
So at runtime C# code gives an serialization error at
"msg_file_s sa = (msg_file_s) bf.Deserialize(ms);"
I thought that it is very hard to memory map structure array.
I need both read and write memory mapped file at both side of C# and C++.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
