Hi, i am working on a usb driver that allocates some memory when the device is opened using malloc.
Now i want user processes to be able to access this memory using mmap and i want to free this memory when it is no longer needed. The problem is that there seems to be no way of knowing for my driver at what time the memory is no longer mapped in a process address space so that i can safely free this memory. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
