stack size during linking time

grzegorzK — Wed, 05 Oct 2011 19:54:57 GMT

Hi all

I wonder if is possible to get a stack size in "c" module during linking time? I am using FreeScale compiler.

e.g.:

================================

extern unsigned __stack_size;

unsigned stack_size()

{

return __stack_size;

}

=====================================

I was looking in linker map file, but seems there is not any object connected with stack size, only with top of stack.

Any clue?

/Regards

Try searching online help for __SEG_SIZE_SSTACK

extern int __SEG_SIZE_SSTACK[];
int a;

{

a = (int)__SEG_SIZE_SSTACK;

}
