I propose the following patch to enhance the EV_SET compat with alternative kqueue/kevent implementations:
http://netbsd.org/~kamil/patch-00133-EV_SET-cpp.4.txt The current problem: Cast of udata from void* to intptr_t shall be done with reinterpret_cast<> otherwise a C++ compiler errors. Defining __REINTERPRET_CAST [1] and using it, did not work as a compiler protested for NULL argument "warning: passing NULL to non-pointer argument". Using double cast __REINTERPRET_CAST(intptr_t, __CAST(void *, (udata))) pacified the warning/error about passing NULL in C++, but it created the problem of calling EV_SET using the native argument type intptr_t. Proposed solution: - use C code as it is - add C++ ifdef block that replaces cast with the C++ feature to overload function with a custom argument; define _EV_SET that accepts void* in udata; hide reinterpret_cast<>() inside the second function Tested by nia@. I would like to pull it into -9 and maybe into -8. [1] #ifdef __cplusplus -#define __CAST(__dt, __st) static_cast<__dt>(__st) +#define __CAST(__dt, __st) static_cast<__dt>(__st) +#define __REINTERPRET_CAST(__dt, __st) reinterpret_cast<__dt>(__st) #else -#define __CAST(__dt, __st) ((__dt)(__st)) +#define __CAST(__dt, __st) ((__dt)(__st)) +#define __REINTERPRET_CAST(__dt, __st) ((__dt)(__st)) #endif
