Hi Nitin,


>>One of the important scenario that you left is indirect function call
>>through function pointer.


Compiler computes the stack requirement of a function while processing
the function definition i.e when it is processing the body of the
function.


Now coming to function pointers i.e. indirect function call I feel that
when we talk of stack requirement of a program we talk in terms of
maximum possible stack space that program will need at run time. It
might happen that few of the functions are never invoked during run
time. Now if user is using function pointers in program in that case we
will be able to tell the maximum stack requirement of the program which
can be less than the actual because one is not sure which function is
invoked at run time.


Thanks and Best Regards,
Jatin Bhateja
