So what is your problem,exactly??

Hello sir/madam

. I am trying to use the calloc and the malloc functions. The calloc and malloc functions are able to allocate the memory upto size of 4K. After this calloc and malloc functions are unable to allocate the memory.
It would be good if someone could provide a clue on to get this to work, so that we can allocate more than 4K of memory.


Any help would be greatly appreciated.


Thanks and Regards

The calloc and malloc functions are able to allocate the memory upto size of 4K. After this calloc and malloc functions are unable to allocate the memory.

I have never heard that before and I have personally used calloc/malloc for allocation into the megabytes.

Where are you getting this 4K limitation from???
