GetFreeMemory

llGetFreeMemory

Summary

Function: integer llGetFreeMemory( );

225	Function ID
0.0	Forced Delay
10.0	Energy

Returns an integer that is the available free space for the current script.

BUG: Instead of returning the free space it returns the amount of free space that has never been allocated by the heap (historic lowest heap pointer minus the stack end pointer). This means that the heap will appear to never shrink in size (when in fact it does grow and shrink to fill the free space).

Caveats

• The function will NEVER return a higher number than any previous call to itself.

Examples

// To show usage of memory by a script, take the free memory from 16k
llOwnerSay("Script uses " + (string)((16384 - llGetFreeMemory())/1024) + " kBytes");

Notes

Because of the implementation of this function it's usefulness is limited. It has been stated that when the LSL VM is moved to Mono that this function will work properly.
