Use the Profiler application's Memory usage captureoption to capture memory usage data on the target device. The data is stored in the profiler data file during a trace operation and can later be viewed in the Analyzer (Figure 1).

The Symbian OS API allocates memory in chunks. A chunk is a region of RAM mapped into contiguous linear addresses. At creation, a process has one to three chunks:
+
+
a stack/heap chunk contains the stack and heap used in the main thread of the process
+
a code chunk exists if the process is loaded into RAM
+
a data chunk exists if the process has static data
+
+
A process can create more chunks, including global chunks accessible by other processes. When a chunk is created, is owned by the current process or the current thread.
