You are right.
I should not try to answer questions based on memory alone :(
I did some digging and here is the long explanation:
The record definition is a formal record definition.
The buffer was defined as 1024 bytes (1K), but this is completely arbitrary.
It could have been [0..0], or [0..MaxInt].
Probably [0..0] would have been better.
I will change it to that.
In practice a FCGI_ContentRecord is never used. A PFCGI_ContentRecord
(pointer to) is used to typecast an array of byte and extract the
necessary header fields from the array.
It's a little like the typinfo structures: they describe memory layouts, but
some structures are just formal, for example
TVmtFieldTable = record
Count: Word;
ClassTab: PVmtFieldClassTab;
{ should be array[Word] of TFieldInfo; but
Elements have variant size! force at least proper alignment }
Fields: array[0..0] of TVmtFieldEntry;
end;
The FCGI_ContentRecord definition should be seen in the same light: a formal
definition.
Michael.
