Sorry... I made a typo in the code... the memcpy row should look like this:
memcpy(&(pn->lock), &(opaque->key), sizeof(struct devlock *)); Forgot to get the pointer's to the variables, and therefore it ended up with a segmentation fault instead... Can you try to change the row and recompile with memcpy again? /Christian -----Original Message----- From: Serg Oskin [mailto:s...@oskin.ru] Sent: Monday, December 22, 2008 12:13 PM To: owfs-developers@lists.sourceforge.net Subject: Re: [Owfs-developers] general protection > Now running CVS-version on 9:30 UTC 2008-12-22 ...
