Sharing memory between processes.

[Shawn Workman]

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?        I have used the shm* functions and from what I see I am limited to the number of shared memory pointers I can have.       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..   Thank you for any insight to this problem.
