How do I check how much memory my application is using?

Integrating the routine below will allow you to track the memory usage of your application:

#include <stdio.h>
#include <stdlib.h>

#include <spi/include/kernel/memory.h>

void print_memusage()
{
uint64_t shared, persist, heapavail, stackavail, stack, heap, guard, mmap;

Kernel_GetMemorySize(KERNEL_MEMSIZE_GUARD, &guard);
Kernel_GetMemorySize(KERNEL_MEMSIZE_SHARED, &shared);
Kernel_GetMemorySize(KERNEL_MEMSIZE_PERSIST, &persist);
Kernel_GetMemorySize(KERNEL_MEMSIZE_HEAPAVAIL, &heapavail);
Kernel_GetMemorySize(KERNEL_MEMSIZE_STACKAVAIL, &stackavail);
Kernel_GetMemorySize(KERNEL_MEMSIZE_STACK, &stack);
Kernel_GetMemorySize(KERNEL_MEMSIZE_HEAP, &heap);
Kernel_GetMemorySize(KERNEL_MEMSIZE_MMAP, &mmap);
#if 0
printf("Allocated heap: %.2f MB, avail. heap: %.2f MB\n", double(heap)/(1024*1024), double(heapavail)/(1024*1024));
printf("Allocated stack: %.2f MB, avail. stack: %.2f MB\n", double(stack)/(1024*1024), double(stackavail)/(1024*1024));
printf("Memory: shared: %.2f MB, persist: %.2f MB, guard: %.2f MB, mmap: %.2f MB\n", double(shared)/(1024*1024), double(persist)/(1024*1024), double(guard)/(1024*1024), double(mmap)/(1024*1024));
#else
printf("MEMSIZE heap: %.2f/%.2f stack: %.2f/%.2f mmap: %.2f MB\n", (double)heap/(1024*1024), (double)heapavail/(1024*1024), (double)stack/(1024*1024), (double)stackavail/(1024*1024), (double)mmap/(1024*1024));
printf("MEMSIZE shared: %.2f persist: %.2f guard: %.2f MB\n", (double)shared/(1024*1024), (double)persist/(1024*1024), (double)guard/(1024*1024));
#endif
}
