Allocate and clear an aligned memory area. Use FDKafree() instead of
FDKfree() for these memory areas.

Allocate aligned memory in a specific memory section.
See FDKcalloc_L() description for details — same applies here.

Free an aligned memory area.

Free aligned memory that was allocated in a specific memory section.

Allocate memory in a specific memory section.
Requests can be made for internal or external memory. If internal memory is
requested, FDKcalloc_L() first tries to use L1 memory, which sizes are
defined by ::DATA_L1_A_SIZE and ::DATA_L1_B_SIZE. If no L1 memory is
available, then FDKcalloc_L() tries to use L2 memory. If that fails as well,
the requested memory is allocated at an extern location using the fallback
FDKcalloc().

brief Read variable of size «size» as little endian. Convert
automatically to host endianess. 4-byte alignment is enforced for 24 bit
data, at 32 bit full scale.
param dst Pointer to memory where to store data into.
param size Size of each item to be read.
param nmemb Number of items to be read.
param fp File pointer of type FDKFILE.
return Number of items read on success and fread() error on failure.

param ptrf Pointer to memory where to read data from.
param size Size of each item to be written.
param nmemb Number of items to be written.
param fp File pointer of type FDKFILE.
return Number of items read on success and fread() error on failure.

Clear memory.
Either use implementation from a Standard Library, or, if no Standard Library
is available, a generic implementation.
The define ::USE_BUILTIN_MEM_FUNCTIONS in genericStds.cpp controls what to
use. The function arguments correspond to the standard memclear(). Please see
MSDN documentation for details on how to use it.

Copy memory. Source and destination memory must not overlap.
Either use implementation from a Standard Library, or, if no Standard Library
is available, a generic implementation.
The define ::USE_BUILTIN_MEM_FUNCTIONS in genericStds.cpp controls what to

brief Print FDK software disclaimer.

Check platform for endianess.

brief Get one ancillary data element.

brief Initialize ancillary data buffer.

brief De-allocate all resources of an AAC decoder instance.

brief Explicitly configure the decoder by passing a raw AudioSpecificConfig
(ASC) or a StreamMuxConfig (SMC), contained in a binary buffer. This is
required for MPEG-4 and Raw Packets file format bitstreams as well as for
LATM bitstreams with no in-band SMC. If the transport format is LATM with or
without LOAS, configuration is assumed to be an SMC, for all other file
formats an ASC.

brief Decode one audio frame

brief Fill AAC decoder’s internal input buffer with bitstream data from the
external input buffer. The function only copies such data as long as the
decoder-internal input buffer is not full. So it grabs whatever it can from
pBuffer and returns information (bytesValid) so that at a subsequent call of
%aacDecoder_Fill(), the right position in pBuffer can be determined to grab
the next data.

brief Get free bytes inside decoder internal buffer.
param self Handle of AAC decoder instance.
param pFreeBytes Pointer to variable receiving amount of free bytes inside
decoder internal buffer.
return Error code.

brief Get decoder library info.

(only some box types are recognized).
