    calloc and realloc

    Hey everyone,

    I'm using calloc to allocate memory and initialize each block in that memory to 0. If I call realloc sometime later to allocate more space, how can I make sure that all the blocks in the extra space are also initialized to 0?

    Right 98% of the time, and don't care about the other 3%.
