Hi All,
Development envrionment: Mac OS 10.4.6 PPC
XCode 2.2
I am developing a device driver for my USB bulk device, using I/O kit framework (its a user-level framework) and wanted your inputs in the following issue:
My application, i.e. user-interface loads the framework which in turn communicates with the device and returns back the data.
I need to achieve synchronization when multiple instances of the applications are running. For example, when we run 2 instances of the application, then each application will load the framework seperately and therefore each will have its own process space.
What are the various ways to achieve synchronization across multipe processes?
Can we have concept of shared memory in this case ?
I tried applying semaphores but failed.
Any pointers, links for the same are most welcome.
Thanks and Regards,
Rohit dhamija
