Hi, I have a module and an application program in user space:
The Module performs the following task: at init it initializes the cpm timer register of the mpc823, such that an interrupt is generated every x microseconds. Thus, I installed an interrupt handling function f that handles the timer interrupts. My problem is that the module / the interrupt handling function should execute a procedure defined in the application program. How can I pass a pointer (which points to that function) from the appl.program to the module, such that the handler can execute this function every x milliseconds? I thought to create a procedure in the module that accepts a function pointer as argument. But how can I achieve, that this module procedure is visible to the application program? Does somebody have a suggestion or know another way to do it? Regards, Juergen ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
