+ *
+ * Only one source file should define PADL_DEFINE_POINTERS before including the header which
+ * defines the functions. This will cause the compiler to dump all of the function pointers
+ * to a single object file and prevent duplicate symbol definitions during link.
+ *
+ * The PADL_FUNC_WITH_RETURN and PADL_FUNC_NO_RETURN macros do two things each:
+ * 1) Define or reference the variable that contains the actual function pointer
+ * 2) Define an inline function to pass control to the real function
+ *
+ * Since the macros redefine the real functions of the same name, the compiler will make
+ * sure that the definitions are the same. If not, it will complain. For this to occur,
+ * the functions MUST be defined in an extern "C" block otherwise the compiler just thinks the
+ * functions are being overloaded.
+ *
+ * The compiler should optimize away the inline function since it just passes control to the real
+ * function and we should wind up with about the same function call we had before, only now it is
+ * safer due to the validation.
+ *
+ * The PADL_FUNC_WITH_RETURN takes 4 arguments:
+ * 1) The return type <---|
+ * 2) The function name | Taken from the real funciton prototype
+ * 3) The function arguments <---|
+ * 4) The argument list to pass to the real function
+ *
+ * The PADL_FUNC_NO_RETURN takes 3 arguments:
+ * 1) The function name <---| Taken from the FFmpeg funciton prototype
+ * 2) The function arguments <---|
+ * 3) The argument list to pass to the real function
+ *
+ * The PADL_FINDSYMBOL macro is responsible for retrieving the address of the real function
+ * and storing that address in the function pointer variable.
