Sixty Four Bit Integer 29 30 (9/14/2009 11:26:13 PM) comp.lang.c There's a type in Java called that is essentially a 64-bit in- teger. Is there a type in C that is also a 64-bit integer? Or, if there isn't, is there a type by some other name that is a 64- bit integer? --... kvnsmnsn (147)

Change in C 67 32 (9/16/2009 11:27:10 PM) comp.lang.c In the thread "When will C have an object model?", I found a message from Mr Heathfield that warrants a deeper discussion. That thread was (for a change) an interesting one. Richard Heathfield a �crit : > >... jacob24 (973)

Buffer growing strategy? 34 20 (9/17/2009 7:32:28 AM) comp.lang.c Hi, I'm implementing a buffer that grows automatically when appending or prepending data. To improve performance, I'm looking into a buffer growing strategy to double the memory (or more generally multiply w... jefdriesen (86)
