calloc()
-
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 !!!
Don't know where to start ?

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

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.

Why on earth would you need
calloc, then?

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. ;)

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.

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