It is OS dependent, like palbano says. I believe Windows allocates 4gb memory for your process, of which 2gb is for you to use and the other for Windows itself. In special circumstances (don't know exactly how anymore) you could change that ratio to 3gb to 1gb in your favor on Windows 2000 (and probably NT).
But don't forget: the actual size you can allocate depends on how large a block of unfragmented unused memory still resides in your process. It's highly unlikely you'll ever get to allocate the full bunch....
