Hi,
It'll be on stack i suppose and in general all variables declared inside a function will be on stack as well.
You can print the address of where a resides and print the value of stack pointer (SP) you then should have the same base address ...
Code:
unsigned long sp(void) {
asm("movl %esp, %eax");
}
void main() {
int *a;
a=malloc(16*sizeof(int));
printf ("addr of a is %p, sp is %p and malloc is %p\n",&a,sp(),a);
}
I'm a new guy to this field and I'm learning a lot about UNIX! Can any explan to me what exactly does 'heap size' mean and how can i increase the size for AIX 4.3.3? (2 Replies)
Hi all,
Thanks 'thehoghunter' and 'hugo' for the comments!
I've to increase the size of the heap size for AIX 4.3.3. Now what's the command that I've and also is it something similar to growing the file system in Solaris (growfs) (1 Reply)
The Resident size(as observed from top) of my process is increasing. But, the behaviour is very random. My process works on request reponse model. So when i put some request load on my process the memory starts increasing. For initial few hours (approx ~3 hrs) it increase at a rapid rate and after... (1 Reply)
Hi All,
We are facing issues on HPUX with the C heap region growing. We use a product for CRM by name ClarifyCRM and it uses a native layer for DB access. so there are best practices in place to actual control memory. recently we have seen issues that the C heap region is growing faster than... (0 Replies)
I want to find the size of the total memory allocated on the heap for the following statement:
int* a = new int;How can I use the sizeof operator for this?
I used:
printf("\t===> %d\n",sizeof(*a));
Is this statement correct?
I have asked the question because when I checked the memory of... (13 Replies)
Hi,
I am new to the linux kernel development area. I want to know what is the difference between kernel mode stack and user mode stack? Does each process has a user mode stack and a kernel mode stack?? Or Each process has a user mode stack and there is only one kernel mode stack that is shared by... (4 Replies)

Heap::Elem::StrRev(3pm) User Contributed Perl Documentation Heap::Elem::StrRev(3pm)NAME
Heap::Elem::StrRev - Reversed String Heap Elements
SYNOPSIS
use Heap::Elem::StrRev( StrRElem );
use Heap::Fibonacci;
my $heap = Heap::Fibonacci->new;
my $elem;
foreach $i ( 'aa'..'bz' ) {
$elem = StrRElem( $i );
$heap->add( $elem );
}
while( defined( $elem = $heap->extract_top ) ) {
print "Largest is ", $elem->val, "
";
}
DESCRIPTION
Heap::Elem::StrRev is used to wrap string values into an element that can be managed on a heap. The top of the heap will have the largest
element still remaining. (See Heap::Elem::Str if you want the heap to always return the smallest element.)
The details of the Elem interface are described in Heap::Elem.
The details of using a Heap interface are described in Heap.
