...between domains. i need to be able to write to a shared memory from one domain and allow other domain(s) to read from it. for example domA is always the writer and domB or domC are always readers. to be able to do that does hypervisor provide anything like "shmget" for domA and "shmat" for domB and domC?:) i''m just reading up grant tables etc where some frames are shared between domains. would grant tables mechanism allow me to do above thing? if so, can domA grant read access to, say 20 frames, for domB and domC upfront and never revoke them? am now...

I want to access the shared memory created by the windows application running under wine with a linux application. Using something like "shmat". Is this possible? Can someone point me in the right direction for this? Thanks in advanced.

...), then stuffs the output into a shared memory segment. This app runs perfectly using Wine on my Linux box(Fedora 12). My own development environment is Java. I need to write a piece of native C code that can get at the shared memory segment that is created by my customer's application using shmat(). Does anyone have any idea how to tackle this issue?

I wonder if the right approach would be to modify add a modified version of the allocVector(SEXPTYPE type, int length) function specifically shared_mem_id = shmget(shared_mem_key, SHM_SIZE, IPC_CREAT); shared = (SEXP) shmat(shared_mem_id, (void *)0, 0); my_allocVector(SEXPTYPE type, int length, SEXP shared) { SEXP s=shared; ....

I've downloaded the latest DB2 client, and its ODBC registration program complains that this is missing. No threads or references here. There didn't appear to be a download for it at M$. A search yielded lots o sites that offered it. Any recommendations? thanks

Moin, I installed liveice as well as 'screen' at a debian maschine, both applications are running fine. But when I try to start liveice in a 'screen' environment then the liveice process ends without an error message: $ /usr/bin/screen -dmS liveice /usr/bin/liveice A prefixed 'strace -f' shows me: [pid 5614] old_mmap(NULL, 167936, PROT_READ|PROT_WRITE,

Linux 2.2 (and probably others) have a deficient mmap which has caused a number of problems (e.g. bug #285). A workaround is in development, but it would be helpful to have a configure test to detect the bad mmaps(). Any takers? -d
