Pathname: s_tDec_Int_File.h
------------------------------------------------------------------------------
REVISION HISTORY
Description: Remove unneeded structure elements, clean up.
Description: Remove block.h, not needed, chains in other not needed files.
Description: Added declaration of scratch memory, scratchTnsDecCoefMem,
which will be utilized by tns_decode_coef().
Description:
(1) Modified to include the lines...
#ifdef __cplusplus
extern "C" {
#endif
#ifdef __cplusplus
}
#endif
(2) Updated the copyright header.
Description: Per review comments...
(1) Removed declaration of unused variable, savedMCInfo
(2) Commented out ADTS related variables.
(3) Slight re-wording of comment for clarity.
Description:
(1) Moved scratch_prog_config into the scratch union.
Description:
(1) Added ltp state variable.
Description: Make tDec_Int_perChan an array of structures.
In the user applications, the malloc command will allocate a
continuous chunk of memory.
Description:
(1) Added the array data_stream_bytes[] to structure tDec_Int_File.
This to support Data Streaming Elements (DSE).
(2) Updated the copyright header.
