+This chapter describes the global functions and macros you use to
+perform memory management. NSPR provides heap-based memory management
+functions that map to the familiar ``malloc()``, ``calloc()``,
+``realloc()``, and ``free()``.

+
+Memory Allocation Functions
+---------------------------
+
+NSPR has its own heap, and these functions act on that heap. Libraries
+built on top of NSPR, such as the Netscape security libraries, use these
+functions to allocate and free memory. If you are allocating memory for
+use by such libraries or freeing memory that was allocated by such
+libraries, you must use these NSPR functions rather than the libc
+equivalents.
+
+Memory allocation functions are:
+
+ - :ref:`PR_Malloc`
+ - :ref:`PR_Calloc`
+ - :ref:`PR_Realloc`
+ - :ref:`PR_Free`
+
+``PR_Malloc()``, ``PR_Calloc()``, ``PR_Realloc()``, and ``PR_Free()``
+have the same signatures as their libc equivalents ``malloc()``,
+``calloc()``, ``realloc()``, and ``free()``, and have the same
+semantics. (Note that the argument type ``size_t`` is replaced by
+:ref:`PRUint32`.) Memory allocated by ``PR_Malloc()``, ``PR_Calloc()``, or
+``PR_Realloc()`` must be freed by ``PR_Free()``.
+
+.. _Memory_Allocation_Macros:
+
+Memory Allocation Macros
+------------------------
+
+Macro versions of the memory allocation functions are available, as well
+as additional macros that provide programming convenience:
+
+ - :ref:`PR_MALLOC`
+ - :ref:`PR_NEW`
+ - :ref:`PR_REALLOC`
+ - :ref:`PR_CALLOC`
+ - :ref:`PR_NEWZAP`
+ - :ref:`PR_DELETE`
+ - :ref:`PR_FREEIF`
