C++ allows one to create types that are pointer types but wrap a primitive pointer to give RAII handling of resources. For example:
class Dvb::FrontendParameters_Ptr {
private:
dvb_v5_fe_parms * ptr;
public:
FrontendParameters_Ptr(FrontendId const & fei, unsigned int const
verbose = 0, unsigned int const legacy = 0);
FrontendParameters_Ptr(FrontendParameters_Ptr const &) = delete;
FrontendParameters_Ptr & operator=(FrontendParameters_Ptr const &)
= delete;
~FrontendParameters_Ptr() {dvb_fe_close(ptr); }
dvb_v5_fe_parms * c_ptr() const { return ptr; }
dvb_v5_fe_parms * operator->() const { return ptr; }
};
Has anyone any experience of doing the analogous thing idiomatically in
D.
I just re-realised I manually constructed a C++ abstraction layer
around some of libdvbv5, so I am going to do the same for D. However
whilst I (sort of) understand doing the wrapping with C++, I am not
sure I have seen anyone wrapping C pointers with RAII in D.
