PtInputCallbackProcF_t, PtInputCallbackProc_t

Type for defining an input callback function

Synopsis:

typedef int PtInputCallbackProcF_t( void *, int,
                                    void *,
                                    size_t);
typedef PtInputCallbackProcF_t *
           PtInputCallbackProc_t;

Description:

These data types define pointers to input callback functions. The PtInputCallbackProcF_t type is the function type that the PtInputCallbackProc_t type points to. This allows you to do something like this:

PtInputCallbackProcF_t my_input_callback;

int my_input_callback( void *, int, void *, size_t ) {
    ...
    }

The compiler should detect any inconsistencies between the two declarations of my_input_callback() and give you an error (which is better than a "pointer mismatch" warning on the call to PtAppAddInput()).
