+ * The Memory Tracker HAL is designed to return information about
+ * device-specific memory usage.
+ * The primary goal is to be able to track memory that is not
+ * trackable in any other way, for example texture memory that is allocated by
+ * a process, but not mapped in to that process's address space.
+ * A secondary goal is to be able to categorize memory used by a process into
+ * GL, graphics, etc. All memory sizes must be in real memory usage,
+ * accounting for stride, bit depth, rounding up to page size, etc.
+ *
+ * Constructor for the interface should be used to perform memtrack management
+ * setup actions and is called once before any calls to getMemory().
+ */
+interface IMemtrack {
+    /*
+     * getMemory() populates MemtrackRecord vector with the sizes of memory
+     * plus associated flags for that memory.
+     *
+     * This function must be thread-safe, it may get called from multiple
+     * threads at the same time.
+     *
+     * A process collecting memory statistics will call getMemory for each
+     * combination of pid and memory type. For each memory type that it
+     * recognizes, the HAL must fill out an array of memtrack_record
+     * structures breaking down the statistics of that memory type as much as
+     * possible. For example,
+     * getMemory(<pid>, GL) might return:
+     * { { 4096,  ACCOUNTED | PRIVATE | SYSTEM },
+     *   { 40960, UNACCOUNTED | PRIVATE | SYSTEM },
+     *   { 8192,  ACCOUNTED | PRIVATE | DEDICATED },
+     *   { 8192,  UNACCOUNTED | PRIVATE | DEDICATED } }
+     * If the HAL cannot differentiate between SYSTEM and DEDICATED memory, it
+     * could return:
+     * { { 12288,  ACCOUNTED | PRIVATE },
+     *   { 49152,  UNACCOUNTED | PRIVATE } }
+     *
+     * Memory must not overlap between types. For example, a graphics buffer
+     * that has been mapped into the GPU as a surface must show up when
+     * GRAPHICS is requested and not when GL
+     * is requested.
+     *
+     * @param pid process for which memory infromation is requested
+     * @param type memory type that information is being requested about
+     * @return records vector of MemtrackRecord containing memory information
+     * @return retval SUCCESS on success, TYPE_NOT_FOUND if the type is not
+     * supported.
