SCIPincludeEventhdlr()

SCIP_RETCODE SCIPincludeEventhdlr	(	SCIP *	scip,
		const char *	name,
		const char *	desc,
		SCIP_DECL_EVENTCOPY((*eventcopy))	,
		SCIP_DECL_EVENTFREE((*eventfree))	,
		SCIP_DECL_EVENTINIT((*eventinit))	,

		SCIP_DECL_EVENTEXEC((*eventexec))	,
		SCIP_EVENTHDLRDATA *	eventhdlrdata
	)

creates an event handler and includes it in SCIP

Note

method has all event handler callbacks as arguments and is thus changed every time a new callback is added in future releases; consider using SCIPincludeEventhdlrBasic() and setter functions if you seek for a method which is less likely to change in future releases

Parameters

scip	SCIP data structure
name	name of event handler
desc	description of event handler
eventhdlrdata	event handler data

Definition at line 8484 of file scip.c.

References checkStage(), FALSE, NULL, SCIP_CALL, SCIP_INVALIDDATA, SCIP_OKAY, SCIPerrorMessage, SCIPeventhdlrCreate(), SCIPfindEventhdlr(), SCIPsetIncludeEventhdlr(), Scip::set, and TRUE.

SCIPincludeEventhdlrBasic()

SCIP_RETCODE SCIPincludeEventhdlrBasic	(	SCIP *	scip,

		const char *	name,
		const char *	desc,
		SCIP_DECL_EVENTEXEC((*eventexec))	,
		SCIP_EVENTHDLRDATA *	eventhdlrdata
	)

creates an event handler and includes it in SCIP with all its non-fundamental callbacks set to NULL; if needed, non-fundamental callbacks can be set afterwards via setter functions SCIPsetEventhdlrCopy(), SCIPsetEventhdlrFree(), SCIPsetEventhdlrInit(), SCIPsetEventhdlrExit(), SCIPsetEventhdlrInitsol(), SCIPsetEventhdlrExitsol(), and SCIPsetEventhdlrDelete()

Note

if you want to set all callbacks with a single method call, consider using SCIPincludeEventhdlr() instead

Parameters

eventhdlrptr	reference to an event handler, or NULL
name	name of event handler
desc	description of event handler
eventhdlrdata	event handler data
