Re: Problems with use of M_NOWWAIT in ATA (w/ demonstration patch)

2003-11-28 Thread Matthew Dillon
All right, here's an example patch. This patch is against the old ATA code in DragonFly but most of the issues are the same with the ATA code in -STABLE and -CURRENT. It does not fix all the problems (which would be a waste since we are about to import ATAng and do not want to

2003-11-28 Thread Matthew Dillon

Thanks a lot for the answer. I will change vfork() with fork(). An another question: in the man page of vfork() it is mentionned that the fork() function has to use _exit(0) too when something wrong with the execve() happens! but in a thread context of my program, the use of _exit() may not be be
