Basically, they convert a lot of short fields to what the manual page calls "longs", but which are actually 32 bit values; makes you wonder where they obtained the name "IPC_64", when it should probably more properly be "IPC_32". They pad it out to 36 bytes by adding two unsigned long fields (32 bit longs); gotta wonder why they didn't stop at 32 bytes... -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
