libctru - How to know when app runs out of memory?

[Gearmo3DS]

Given this snippet:

Code: Select all

    u32 totalMemory, freeMemory;
    freeMemory = osGetMemRegionFree(MEMREGION_APPLICATION);
    totalMemory = osGetMemRegionSize(MEMREGION_APPLICATION);

I noticed that freeMemory always returns zero.

Should I only use `linearSpaceFree();` instead?

You know when an app runs out of memory when you can't allocate any more. It isn't possible to know whether or not an allocation will succeed before attempting to allocate nor is it possible to determine how much memory is free in the system.
