Thanks for your reply!
I actually tried it using sleep( ) before, but that didn't have any effect. Using wait( ), as you suggested, did the trick. Now I have a new problem: If I pass low addresses as third parameter, I always get ``Bad address'' errors. While trying to find the root of this problem, I happened to pass the uninitialised variable ``i'' as address (I used it as loop counter before and when I commented that out, the value became, of course, undefined :-) )...
It worked! Strangely, the value of ``i'' was 671482112.
Quotation from the man page:
Quote:
The addr argument specifies the address (in the traced process' virtual address space) at which the read is to be done. This address does not have to meet any alignment constraints.
I don't believe that my tiny ``foobar'' program uses > 640mb of memory. Even if this was an absolute address (contradicting the man page), I don't have that much. While I'm typing this, I have the program trying all ``addresses'' from 0 to 1000000000 - It's at 115xxxxxx now and no ``address'' was valid. What the heck is going here?
I'm trying to unmount a file system, but umount says the device is busy. A fuser -c /myfs tells me that nothing on this fs is in use. Any idea?
Oh, and btw, why isn't my signature beeing displayed? Show user's signature is enabled and I have entered one :/ (10 Replies)
