Alex,
Please respond to the list instead of my personal address.
Nevertheless, if MYSQL_TYPE_LONG is the datatype for a table field,
it would always -have- to be the same size, cause different clients can
connect (if not being embedded), wouldn't it?

Hi Martijn,
I made an embedded mysql server. The API for the clients to my server use the standard
mysql client C API. If clients pass bad pointers to the server I don't want the server to
crash. So the server knows about all valid mysql connections. If a bad mysql pointer is
passed in, it can detect that. So when I save valid pointers when a connection is made I
like to save it as a MYSQL_TYPE_LONG. The client and the server has to run on similar
type machines. 64bit client with 64bit server and 32bit client with 32bit server, no
mismatch. The Long size in a 32bit machine is 4 bytes but in a 64bit machine is 8 bytes.
So I wanted to avoid conditionals for building for a 64bit machine.

Ehm, wouldn't that like, totally fail if -saved- by a 64bit machine and -read- by
a 32bit machine if that were the case?
Perhaps you should explain in more detail what you're trying to do?
