Profiler.GetMonoUsedSizeLong

Returns

long A long integer value of the memory in use.

Description

The allocated managed-memory for live objects and non-collected objects.

This function returns the amount of allocated managed-memory for all objects, both live and non-collected. Always call GC.Collect() before calling this function as non-referenced objects will still take up space until they are collected by the garbage collector (GC). Note that this will return an ever increasing value until GC.Collect() is called.

Note: This API is available even when the rest of Profiler class is not available (ie, in release builds).
