Hi,
Is there any way to get information about stack and heap at runtime in a C function? I'm looking for a var/table/way to get Stack_Base, Heap_base, Stack_limit and heap_limit at runtime.
That's because I'm trying to make a very very small multitasking kernel for Cortex-M3 and I need somehow to know the Stack memory avail for my alloc routines.
Regards,

Dear Tamir,
There is no problem with that. I just want to avoid the "compile time alloc" thing. Of-course if I can not find a solution i'll use something like that
uint8_t kstack_privil[KERNEL_PRIVILEGED_STACK_SIZE]; uint8_t kstack_unprivil[KERNEL_UNPRIVILEGED_STACK_SIZE];
And I'll make the allocator to give stack slices from these tables.
Christos.
You can always allocate memory from the heap. But remember that systems that are built using such a kernel will require the have heap space allocated as well.
