If you want to know whether it is possible to allocate more memory under Windows, ask in a Windows group like news:comp.os.ms-windows.programmer.win32. For the same information about Free BSD, ask in a BSD group or mailing list. This is not a limitation of the C language, so the language can't tell you how to overcome it, if indeed you can at all. Maybe you can't. -- Jack Klein Home: http://JK-Technology.Com FAQs for comp.lang.c http://www.eskimo.com/~scs/C-faq/top.html comp.lang.c++ http://www.parashift.com/c++-faq-lite/ alt.comp.lang.learn.c-c++ http://www.contrib.andrew.cmu.edu/~a...FAQ-acllc.html |
