GDGetOverflowCallback

C Specification

#include <revolution/gd.h>

typedef void (*GDOverflowCallback)(void);

GDOverflowCallback GDGetOverflowCallback();

Arguments

None.

Return Values

A pointer to the current overflow callback.

Description

This function can get a pointer to the current overflow callback that the GD library will invoke when a graphics display list overflows. Overflow is only detected if the current location pointer is or will be past the end of the associated memory buffer when attempting to write to a GDLObj.

If an overflow callback is not declared, the default overflow process will force an assertion failure. (Debug build only.)
