Description

This function is identical to the C library fopen function, but goes via the MGL's internal file handling function pointers, which by default simply points to the standard C library functions. These functions are intended to allow the application programmer to override all the MGL file I/O functions with MGL_setFileIO, for custom I/O handling.
