<DIV>Hi Dalibor,</DIV>
<DIV> </DIV>
<DIV> The problem with using dprintf and configure options in this scenario is</DIV>
<DIV>there will be a lot of information and parameters printed to the file which I may not need.</DIV>
<DIV>I have put some specific hooks in the JVM(these are the only things that I want) using fprintf with which I'm unable to get it in the correct format. I also used flock but with no result. Could you please help me with any ideas other than dprintf and configuring in the debug mode.</DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV>

different threads calling your function at <BR>the same time. Try using dprintf, like other debugging output does.<BR><BR>Looking at kaffe/kaffevm/kaffe-gc/gcmem.c, it seems like that sort of <BR>output (size and location of allocated blocks in the gc) is already <BR>printed by -vmdebug GCALLOC. You have to enable debugging in configure, <BR>though. And you'd have to deal with a slightly different output format.<BR><BR>best of luck for your work,<BR>dalibor topic<BR></BLOCKQUOTE></DIV><p>
