use free -m and/or brk

Hi,

You can get the system memory available by the command:

#free -m

Also if you want to know the memory available to any particular process, you can use Zero increment to the sbrk() system call. Check the man page for usage...

Happy programming...

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. AUTHOR
