Function Documentation

assert1() [1/3]

UtilExport int assert1	(	int	line,
		const char *	file,
		const char *	function = NULL,
		const char *	expr = NULL
	)

Method to be called to signal a violation of some assumption in the code.

This method should not be called directly, but rather via the various assertion macros such as DbgAssert, MaxAssert, DbgVerify, etc.

Parameters

line	- the line number where the assertion occurred
file	- the file path and name where the assertion occurred
function	- the non-decorated name of the function in which the assertion occurred
expr	- the expression that was asserted

Returns

Currently, this method either returns TRUE or it triggers the shutdown of 3ds Max

assert1() [2/3]

UtilExport int assert1	(	int	line,
		const wchar_t *	file,
		const wchar_t *	function = NULL,
		const wchar_t *	expr = NULL
	)

assert1() [3/3]

UtilExport int assert1	(	int	line,
		const wchar_t *	file,
		const char *	function = NULL,
		const wchar_t *	expr = NULL
	)

SetAssertCB()

UtilExport CAssertCB * SetAssertCB

(

CAssertCB *

cb

)

Sets a callback object that allows for performing a custom action when an assertion fails (is triggered).

A plugin can supply an object that allows for executing a custom action when an assertion fails in 3ds Max. For details on the extent of possible customization see class CAssertCB. Currently, only one callback object can be active at any given time. This means that the callback installed by a plugin can be de-installed by another plugin. Thus, plugins should keep their callbacks active for as short of a time period as possible, and restore the previous callback object when they de-activate their own.

Parameters

cb	- The new callback object to use

Returns

The old callback object or NULL if there's none set
