Hi
I would like to be able to checkpoint a process in a segv handler. At a
later time in the process execution, most likely also during a segv, I would
like to rollback using the previously saved checkpoint.
My work involves memory management and it would be ideal if I could
checkpoint/rollback in the segv handler such that a rollback could be
performed by copying the saved stack,etc while in the handler. This means
that in terms of program execution involving a rollback, the entry into the
handler will not be consecutive with the exit from the handler.
Does anybody know if the kernel segv mechanisms will allow this?
Jon
