How do you find the available system memory using a c or c++ program??? is there any command.. any help would be greatly appreciated.. thanx Rrrrrrrrrrrromeo

You can use the ''free'' command to get a breakdown of current memory status:
$ free
total used free shared buffers cached
Mem: 255860 251336 4524 0 10532 149312
-/+ buffers/cache: 91492 164368
Swap: 393112 260 392852


But I don''t know of an equivalent function call.

-Sypro

Also, you can use ''top'' to see how much cpu and memory a program is using...

/Mikael

I don''t know of a function either, but you can manually parse /proc/meminfo (assuming Linux with /proc enabled).

IRIX 6.5, SunOS 5.2 : getrlimit() (in sys/resource.h)
I can''t get to the man pages on the local linux box.

Check your man pages for details ( brk() and sbrk() are a good starting point )
