I need the available memory (heap). At that time the functions

This functions produce allways zero!! What can I do? What is wrong?
I use fpc version 2.2.0 [2008/05/27] for i386.
On which OS? And what happens if you allocate some memory at the start
of your program?
Anyway, even if it would return non-zero values, the information would
be next to useless. The reason is that on modern OS'es, available
physical memory is dynamically divided between the disk cache and
applications, with a lower limit on the disk cache. What would you
expect memavail to report? The current amount of really "free" memory?
Free + cache? Free + part of cache? Free + non-wired (i.e., swappable)
+ part of cache? Free + non-wired + part of cache + swap space?
The information provided by GetFPCHeapStatus is only useful to get
statistics about the heap manager, and not to get any information
about the system you are running on.
