Subject:   mmap MAP_INHERIT question.
Message-ID:  <20010823131625.A26135@cicely20.cicely.de>

next in thread | raw e-mail | index | archive | help
I do the following:
        buf = (char*)mmap(NULL, BUFSIZE, PROT_READ | PROT_WRITE,
	    MAP_ANON | MAP_INHERIT | MAP_SHARED, -1, 0);

Now I vfork/execve a child.
But the child can't access the mmaped memory.
It was my understanding that MAP_INHERIT | MAP_SHARED keep the memory
over the execve.
