On many systems it is a mount point for a tmpfs filesystem. This is required by some POSIX shm implementations (shmopen(), etc.). I think it is starting to be created automatically by some (many?) current distributions. Last year, Paul Davis wrote a version of JACK (in CVS only) that required POSIX shm. There was massive confusion at the time, because many systems did not have the appropriate mount configured. And, that is not the kind of thing JACK's `make install' should do. > My LADSPA plugin would allocate a segment of shared memory from "/dev/shm". > That is possible because most likely all Linuxes have that device. > Then somehow I create a backdoor for LADSPA controls.

Nice. Personally, I think a socket interface would be better, though. -- joq
