Hi: In the idl file i defined an interface including a function declaration like this: int foo([in] arg1, [in] void *( * start_routine)(void *), [in] arg2);
My aim is to define a method which includes a function pointer I define the function name and function parameters by myself. But when I compile there is error.
I checked out the dice manual there is nothing about how to deal with function pointer in idl file. Is this style supported by dice IDL ? If it supports how could I do?
What exactly are you trying to do?
I try to encapsulate the pthread function with some l4 thread functions. In Linux the pthread definition is like this: int pthread_create (pthread_t *__restrict __threadp, __const pthread_attr_t *__restrict __attr, void *(*__start_routine) (void *), void *__restrict __arg) __THROW; So in IDL file I define the similar style but compilation has some errors. Maybe I must consider other solutions.
Why do you need an IDL interface for starting a thread? Can't this just be implemented as a C function? You can have a look at l4/pkg/thread to see how the L4 thread library is implemented.
