+Description
+===========
+
+Traffic Server provides a number of routines for allocating and freeing
+memory. These routines correspond to similar routines in the C library.
+For example, :func:`TSrealloc` behaves like the C library routine :func:`realloc`.
+There are two reasons to use the routines provided by Traffic Server. The
+first is portability. The Traffic Server API routines behave the same on
+all of Traffic Servers supported platforms. For example, :func:`realloc` does
+not accept an argument of :data:`NULL` on some platforms. The second reason is
+that the Traffic Server routines actually track the memory allocations by
+file and line number. This tracking is very efficient, is always turned
+on, and is useful for tracking down memory leaks.
+
+:func:`TSmalloc` returns a pointer to size bytes of memory allocated from the
+heap. Traffic Server uses :func:`TSmalloc` internally for memory allocations.
+Always use :func:`TSfree` to release memory allocated by :func:`TSmalloc`; do not use
+:func:`free`.
+
+:func:`TSstrdup` returns a pointer to a new string that is a duplicate
+of the string pointed to by str. The memory for the new string is
+allocated using :func:`TSmalloc` and should be freed by a call to
+:func:`TSfree`.  :func:`TSstrndup` returns a pointer to a new string that
+is a duplicate of the string pointed to by str and size bytes
+long. The new string will be NUL-terminated. This API is very
+useful for transforming non NUL-terminated string values returned
+by APIs such as :func:`TSMimeHdrFieldStringValueGet` into NLL-terminated
+string values. The memory for the new string is allocated using
+:func:`TSmalloc` and should be freed by a call to :func:`TSfree`.
+
+:func:`TSstrlcpy` copies up to size - 1 characters from the NUL-terminated
+string src to dst, NUL-terminating the result.
+
+:func:`TSstrlcat` appends the NUL-terminated string src to the end of dst. It
+will append at most size - strlen(dst) - 1 bytes, NUL-terminating the
+result.
+
+:func:`TSfree` releases the memory allocated by :func:`TSmalloc` or :func:`TSrealloc`. If
+ptr is :data:`NULL`, :func:`TSfree` does no operation.
