Hi,
I've got gcc running on a Daul Xeon (1Gb Ram ) server. Problem is I can't seem to have arrays bigger than 10 MB - as in eg:
char temp[9000000];
is allowed, but nothing bigger - otherwise I get a segmentation fault. But I need to open files up to 20 - 30 MB in size (email inboxes) to scan them for attachments - and remove the attachment - primitive Anti-virus program I'm writing.
How do I get c programs to allow much bigger arrays?
thanks.
Well you should be using malloc to allocate the space you need on a per attachment basis, rather than setting some large upper bound.
As for the other problem, is this a global array or a local array?
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Be sure to free what you malloc.Code:char *temp = malloc( 1000000000 ); if( temp == NULL ) { printf("Malloc failure.\n"); exit(0); }

Curses, foiled again!

Quzah.
Hope is the first step on the road to disappointment.
Many thanks!
just so you know, most modern operating system limit the amount of memory one process user can own, unless of course you are root (or administrator).
