<item>This function is of less use than usually assumed, since the returned
heap space may be available but not in one block. So even if this function
says that several times more heap space is available than needed, <ref

pointer to it. On error (not enough memory available), <tt/calloc/ returns
<tt/NULL/.

<item>Clearing the memory may not have the expected effect on all platforms:
pointers in the block may not be <tt/NULL/ and floating point variables may
not be zero (0.0). In other words: The "clearing" effect of this function
should be used with care for portable programs.

be used in presence of a prototype.

pointer you're passing somewhere else, otherwise
