RTOS/TMS320C6670: Programmatically count SYSBIOS Heaps and get their handles

Hello!

Is there a way know number of heaps created in SYSBIOS project and get their handles for further mem stat query?

I found internally heap handles are collected in ti_sysbios_heaps_HeapMem_Object__table__V. I hope there is some simple interface to evaluate that array.

Thanks in advance.

HeapMem_Object_count() gives count.
HeapMem_Object_get( NULL, heap_idx ) gives handle for the index. For some reason I see no names, better say see "unnamed instance", but that enough for me to proceed.

You found the right APIs. The following will get all the created HeapMem objects.

int i;
HeapMem_Object *obj;

for (i = 0; i < HeapMem_Object_count(); i++) {
obj = HeapMem_Object_get(NULL, i);
}

Similarly there is a HeapBuf, HeapMultiBuf, etc. functions if you have those heaps in your system also.

A name is not required when a heap is created. For example, the default one that the kernel creates does not have a name.

Note: the above code does not find constructed HeapMem (i.e. HeapMem_construct). For more details about constructed objects, refer to this page: processors.wiki.ti.com/.../TI-RTOS_Object_Creation_Comparison
