GetArrayAllocatedSizeMBS(v as variant) as integer   Deprecated

Type Topic Plugin Version macOS Windows Linux iOS Targets
global method XojoRuntime MBS Util Plugin 20.0 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
This item is deprecated and should no longer be used.
Queries allocated array size in bytes.
Example 
Dim a() As Integer // 8 byte per integer in 64-bit

System.DebugLog "allocated: "+Str(GetArrayAllocatedSizeMBS(a))

Redim a(9) // changes to 80 bytes

System.DebugLog "allocated: "+Str(GetArrayAllocatedSizeMBS(a))

Redim a(19) // changes to 160 bytes

System.DebugLog "allocated: "+Str(GetArrayAllocatedSizeMBS(a))

a.Append 123

System.DebugLog "allocated: "+Str(GetArrayAllocatedSizeMBS(a))
// shows 288, adds space for 16 more values

This function uses internal knowledge of the array layout in memory.
So this will break in case a future Xojo version changes the layout.
Please use only carefully for debugging.

Stopped working on Windows in recent Xojo versions, so we deprecated it.
