Using Memory

This section describes how you can use the Memory Manager to perform the most typical memory management tasks. In particular, this section shows how you can

set up your application heap at application launch time
determine how much free space is available in your application heap
allocate and release blocks of memory in your heap
define and install a grow-zone function

The techniques described in this section are designed to minimize fragmentation of your application heap and to ensure that your application always has sufficient memory to complete any essential operations. Many of these techniques incorporate the heap memory cushion and emergency memory reserve discussed in "Low-Memory Conditions," beginning on Low-Memory Conditions .

This section describes relatively simple memory-management techniques. Depending on the requirements of your application, you might want to manage your heap memory differently.
