History of expand

== Syntax ==

:int expand(int pointer, int size)

== Arguments ==

:pointer

::Pointer to the block of memory to expand

:size

::The new size of the memory block, in bytes

== Return ==

:A pointer to the resized block of memory, or NULL if there was an error resizing the memory block.

== Description ==

:Resizes a block of memory to a new, larger size. expand cannot be used to make a memory block smaller (use realloc for this instead). expand can only be used to expand memory "in place" - that is, without moving the memory block to another position in memory. For this reason, expand is not always able to give you the maximum expansion that you ask for, so be sure to check the size of the new block by using msize.

== Example ==

== Also see ==

:malloc, realloc, msize, free
