I'm looking over dyld's code to insert libraries and perform the
linking, it seems to be based off mmap() and pmap(), right?.
Does it rely on shared region mappings for libraries inserted by the
user or via some of the environment variables?
Also, I would like to know what is the best method and available API
for retrieving the corresponding vnode for a specific file descriptor
in a process. I will try to look this up on my own through the sources
but I guess it might be helpful to other people reading the list and
save them some time.
cheers,
-- John
