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?

Database questions? Check the forum: http://www.databasedevelopmentforum.com 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.

If this type is 4 bytes on a 32bit machine and 8 bytes on a 64bit machine will make it much easier. 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?
