IntHandleManager Struct Reference

Overview

State for managing generic integer handle values.

Data Fields
int	last_handle
	The last handle that was handed out, or -1 if none have been handed out yet.
int	max_value
	Determines a custom wrap-around point. More...
bool	check_value_in_use
	Optimize the handle generation algorithm by tracking whether the handle value has wrapped around. More...
HandleValueInUseFunction	value_in_use
	Function pointer to determine if a handle value is currently in use. More...
void *	context
	A context passed to the value in use function.

Field Documentation

check_value_in_use

bool check_value_in_use

Optimize the handle generation algorithm by tracking whether the handle value has wrapped around.

If not, this is false because there's no need to check if the new handle is in use. This becomes true when the handle value wraps around.

max_value

int max_value

Determines a custom wrap-around point.

It will be ignored if it's negative. Otherwise it represents the highest allowed handle value.

value_in_use

HandleValueInUseFunction value_in_use

Function pointer to determine if a handle value is currently in use.

Used only after the handle value has wrapped around once.
