QTMTB 33 - QuickTime Movie Toolbox & Global Variables (1-May-95)
Q The QuickTime Movie Toolbox documentation states that the Movie
Toolbox maintains a set of global variables for every application using it.
Since our application is running low on global data space, we'd like to know
how much global memory is required for these variables.
A The information maintained by the Movie Toolbox is not kept with the
application's global variables, and the handle created by the EnterMovies call
is stored in the system heap, not in the application heap. Therefore, you don't
have to allocate space in your application for these variables, and this
initialization does not affect your A5 world either. EnterMovies initializes
everything, which includes setting up the necessary data space and creating a
handle to it.
