WebMay 1, 2014 · Included below is the data I’ve collected based on creating and placing shared pointers in a fixed length array. I’ve been comparing compile times using TSharedPtr against compile times using std::shared_ptr. All shared pointers are created and placed into the arrays individually, not within a loop (see code at the end of post). Web1 day ago · Strings. Ultra Engine uses wide strings wherever possible. Lua only supports narrow strings, but UTF-8 text can be encoded in them. When a C++ function is called from Lua, if it is possible for the returned string to contain special characters, the function should always return a wide string converted to UTF-8: Lua doesn't recognize the Ultra Engine …

"WebDec 29, 2024 · C Shared Ptr. This project aims to take std::shared_ptr from c++ and implement it the c way, kind of similar to what gnome glib has done in GObject. It can allocate the memory based on length, which is similar to Allocator in c++, and can take a handler -- a function pointer to call before the memory is freed, as a replica of Deleter.
