Hi,
I have solid background on GNU tools -but IAR... anyway
How to extract a HEAP pointer in IAR C/C++? I have my own malloc routines (i don't use stdlib), so I need that value from xlink.
Trick like
-D_hea=3DHEAP
and in C extern _hea; .=2E .=2E printf("%x",&_hea);
doesn't work :) (but it works for -D_hea=3D123)
Maybe someone with bigger IAR background could help. Thanks for any hint. Arch is AT91sam7 but I think this is irrevelant.

Hello,
Enable language extensions and try the following:
#pragma segment=3D"HEAP"
int main ( void ) {
unsigned int startOfHeap =3D __sfb("HEAP"); unsigned int endOfHeap =3D __sfe("HEAP"); unsigned int heapSegSize =3D __sfsize("HEAP");
printf("Start of heap: %x\n", startOfHeap); printf("End of heap: %x\n", endOfHeap); printf("Heap size: %x\n", heapSegSize);
return 0;
}This assumes you defined HEAP as a segment in the linker command file or using the "@" symbol.
