+PR_Realloc
+==========
+
+Resizes allocated memory on the heap.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <prmem.h>
+
+   void *PR_Realloc (
+      void *ptr,
+      PRUint32 size);
+
+
+Parameters
+~~~~~~~~~~
+
+``ptr``
+   A pointer to the existing memory block being resized.
+``size``
+   The size of the new memory block.
+
+
+Returns
+~~~~~~~
+
+An untyped pointer to the allocated memory, or if the allocation attempt
+fails, ``NULL``. Call ``PR_GetError()`` to retrieve the error returned
+by the libc function ``realloc()``.
+
+
+Description
+~~~~~~~~~~~
+
+This function attempts to enlarge or shrink the memory block addressed
+by ptr to a new size. The contents of the specified memory remains the
+same up to the smaller of its old size and new size, although the new
+memory block's address can be different from the original address.
