It MUST be C++ as this is the Visual C++ / MFC board :)

It may be that you want to much memory so the working set memory is fully used. There is a compiler option to tweak it, but i dont know which.

here is a scoop : The Visual C++ compiler also compiles C code ! ;P

Here's another scoop. This is the C++/MFC board, C questions do not belong here. So it's irrelevant whether the VC++ compiler can compile C code. :-D

ok, and tell me where you ask C question on CP elsewhere that this board ? :confused::~

Why on earth would you need calloc, then?

then what the hell is a calloc() call doing on a C++ code ? C++ deprecates the use of C memory management such as malloc, calloc, realloc and free. instead, you have to use new and delete, and you MUSTN'T miw the two ways together !!!

Yes, But interesting to see, why he is facing problem. Strange that people expect help without giving sufficient information.

It may be a legacy product that has been ported to the new compiler.

There could be any nuber of reason why calloc() would fail. At the point of failure, what values are being passed to it?

He would have told us that, right?:suss: But then, if he would have been really interested in help, he would have given us enough information to help him!:rolleyes:

Not necessarily.

You are making assumptions. Plenty of folks may genuinely want help but may not know how to properly ask for it. The same can be said for folks that may genuinely want to provide help but may not know how to properly do it. ;)
