There are a few potential reasons why binding Raylib's GetMousePosition() to Lua using Lua C API could result in a memory leak, including:

  1. Not properly managing memory in the binding code: If the binding code does not properly manage the memory that it allocates when calling GetMousePosition(), it could lead to memory leaks. For example, if the binding code mallocs memory to store the return value of GetMousePosition() but never frees that memory, it will leak.

  2. Using incorrect Lua API functions: The Lua C API provides a variety of functions for interacting with Lua values and executing Lua code. If the wrong functions are used in the binding code, it could lead to memory leaks. For example, if the binding code incorrectly uses luasetfield() instead of luaLsetmetatable() to associate a Lua table with a C userdata type, it could lead to memory leaks.

  3. Improperly handling Lua garbage collection: Lua employs a garbage collector to automatically free memory that is no longer in use. If the binding code does not properly handle Lua's garbage collection, it could lead to memory leaks. For example, if the binding code creates a Lua object that references a C object, but does not properly unregister the C object from Lua's garbage collector, it could leak memory.

Overall, it's important to carefully review the binding code and ensure that proper memory management and Lua API usage best practices are being followed to avoid memory leaks.
