We are trying now to make some example programs with netmemoryserver, which provides shared memory for several tasks, and came across some problems. After we have created netmemory object with the help of netmemory_create call, we try to check_in with the help of netnameserver ( netname_check_in call ), but can't success. We receive netname_check_in (ipc/send) error: invalid port right and netname_look_up error: name not checked in. Each task must find its local netmemory server with the help of netname_look_up call, parent task then must success in check_in, and if it happens, each task must call netmemory_cache on the local server with the netmemory object to obtain a local mach memory object corresponding to the netmemory object. After that each task must be mapped to the virtual memory by vm_map call. If somebody knows how to solve our problem, please help us. We would very much appreciate this and would be also very thankful if somebody can send to us more manual or other guide literature on netmemoryserver. Alex Heifetz.
