Untyped Allocation API.

Defines the 'C-style' part of the API, where memory management is fully untyped (i.e. done with void pointers and explicit size values).

This API should usually not be used anymore in C++ code, unless some form of raw memory management is necessary (e.g. for allocation of various ID types based on their IDTypeInfo::struct_size data).

◆ memory_usage_peak()

size_t memory_usage_peak ( void )

Get the approximate peak memory usage since the last call to memory_usage_peak_reset. This is approximate, because the peak usage is not updated after every allocation (see #peak_update_threshold).

In the worst case, the peak memory usage is underestimated by peak_update_threshold * #threads. After large allocations (larger than the threshold), the peak usage is always updated so those allocations will always be taken into account.

Clear the listbase of allocated memory blocks.

WARNING: This will make the whole guardedalloc system fully inconsistent. It is only indented to be called in one place: the destructor of the #MemLeakPrinter class, which is only instantiated once as a static variable by MEM_init_memleak_detection, and therefore destructed once at program exit.
