Hello all:
I am about to put some final touches on my ImageMagick Inspector
before it's first release. I would like to know if there is something
equivalent to /dev/shm in MAC OS X? If not, it there a default temp
dir?
As I understand it, on Linux /dev/shm is a 'filesystem' which represents
the virtual memory. There's no such thing on OS X; the VM subsystem is
handled by a (potentially arbitrarily large number of) pager
process(es); and the default OS X pager actually uses the root
filesystem. If you want chunks of shared memory then you can use the
shmget(2)/shmat(2) family of functions. Or you could create a named shm
object with shm_open(2), delete it with shm_unlink(2).
