Yes. Search for LoadAccelerators() and TranslateAccelerator().

Hi
I have used many times calloc().But this time it is going fail.
What may be the reason when calloc() fails(return bad pointer)
Thanx

are you coding in C or C++ ?
|
|
|
|
|
It MUST be C++ as this is the Visual C++ / MFC board 
|
|
|
|
|
here is a scoop : The Visual C++ compiler also compiles C code ! 
|
|
|
|
|
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.

|
|
|
ok, and tell me where you ask C question on CP elsewhere that this board ?  
|
|
|
|
|
I'd say the soapbox

There is such a place: http//cboard.cprogramming.com --- Purely 'C'.

Why on earth would you need calloc, then?

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

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

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.

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 !!!

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.

Can you show code, that is failing ?

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

Sometimes I wonder why you are a CP MVP.
I work with a large amount of legacy C code that use malloc/calloc/realloc/free I cannot, will not change that because it works and has been working for the last few years.
The question is valid, albeit not well "asked", in this forum.

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

If it returns NULL, it is a failure, like an out-of-memory or out-of-address-space condition. If it returns a non-NULL value, but things crash when you try to use it (i.e. it is truly invalid), then I would offer that the heap information used by calloc(...) is messed up,or you are going too far with the pointer returned.
Although, since calloc(...) has to actually touch the memory to initialize it to zero, it should crash within the call to calloc(...) if the memory it allocated is really invalid.
So, what do you mean by "returns bad pointer"?
Peace!
