Could someone give me a hint? Is it simply a matter of > undefining functions that are not present in -stable? In -current, we modified FILE (/usr/include/stdio.h) and added (or changed) a field to use for holding a mutex that is used by flockfile (lib/libc/stdio/_flock_stub.c). We broke the ABI in order to do this, and it was very painful (just search for "the whole stdio mess" or something like that in the -current archives). You cannot do this for -stable. You're going to have to keep the hashtable method of locking FILEs. -- Dan Eischen To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
