C++ memory limit ?
 

I am unable to allocate more than 2.4G of memory for a C++ program
though I have aprox. 4G of physical memory. I am using g++ on a RH9
box.

thanks,

Ask in a Linux newsgroup.

Memory allocation details are Operating System specific.

Most Unix/Linux systems have a per-process memory allocation
limit to prevent a single program from using all of the
resources (thereby starving other running programs).

As others have pointed out, this is platform-dependent but 2.9 seems
about right. Most Linuxes split the address-space into 1GB for kernel
and 3GB for the app, Windows usually split it 2/2GB. Notice that those
3GB is the total amount available to the app not how much you can
allocate, some of it goes to storing the actual application and such.
