- 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.
