+ REVISION HISTORY
+
+ Description:  Copied from aac_decode_frame
+
+ Description: Cleaned up.
+
+ Description: (1) use UInt32 to replace size_t type
+              (2) memory of tDec_Int_File is splitted into 3 pieces,
+                  sizeof(tDec_Int_File) is only part of the total memory
+                  required. The additional memory required to decode per
+                  channel information is allocated by a DPI call outside this
+                  API
+
+ Who:                                   Date: MM/DD/YYYY

+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs: None
+
+ Local Stores/Buffers/Pointers Needed: None
+
+ Global Stores/Buffers/Pointers Needed: None
+
+ Outputs:
+    size = amount of memory needed to be allocated by the calling
+        environment.
+
+ Pointers and Buffers Modified: None
+
+ Local Stores Modified: None
+
+ Global Stores Modified: None

+ FUNCTION DESCRIPTION
+
+ This function returns the amount of internal memory needed by the library.
+ Presently this is a constant value, but could later be more sophisticated
+ by taking into account mono or stereo, and whether LTP is to be used.
