And shared memory has proven itself to be a viable candidate for insertion into the name space. I didn't say that every application of an IPC mevchanism should have its own entry in the name space. Creating a file for each element in a shared memory region makes about as much sense as creating a file for each message in a pipe. But the region itself should be visible from the outside. -- Peter da Silva. `-_-' +1 713 274 5180. 'U` peter@ferranti.com Volume-Number: Volume 21, Number 201
