| Hello,
| I am coming up against a road block in porting an application from
| a win32 platform to FreeBSD. The problem I am having is due to the
| fact that FreeBSD protects it's memory more that NT for example.
|
| Is there a way to give a client app access to another apps memory?
| the way it is done in the win32 app is to basically have the client
| check for the existance of the server if it exists it grabs a pointer
| to it's memory and therefore gains access to all the functions that
| the server has in memory as well as data structures.
|
| Is there anyway to do this using FreeBSD 4.0 Stable?
|
You could ask the server for it, via e.g. RPC calls, or simple sockets.
You could mmap it to/from a file and load up the current state from
the file if it exists (or share FDs if the server forks the client).
| I have used the shm* functions and from what I see I am limited to
| the number of shared memory pointers I can have.
Do you want to share what the server has in a read-only fashion,
or you want all processes to get their own copy, or you want read-write
to all processes?
| I would really appreciate any help that could be provided here.
| I have been looking at the possibility of an lkm but hear that this
| can cause the system to become unstable..
Development might be fun, but, once its done it should be fine.
