Collectgarbage

Available since: Gideros 2011.6

This function is a generic interface to the garbage collector. It performs different functions according to its first argument, opt:

"stop": stops the garbage collector.
"restart": restarts the garbage collector.
"collect": performs a full garbage-collection cycle.
"count": returns the total memory in use by Lua (in Kbytes).
"step": performs a garbage-collection step. The step "size" is controlled by arg (larger values mean more steps) in a non-specified way. If you want to control the step size you must experimentally tune the value of arg. Returns true if the step finished a collection cycle.
"setpause": sets arg as the new value for the pause of the collector. Returns the previous value for pause.
"setstepmul": sets arg as the new value for the step multiplier of the collector. Returns the previous value for step.
