Function Documentation

QDF_acdCtx* QDF_acdCtxConstruct (  QDF_acdCtx *  ctx, unsigned int  level, void *  prm, const QSE_ctx *  qse )

Constructs (initializes) the specified ACD decoding context structure. Returns: Pointer to the context structure to construct Parameters: ctx  The context structure to construct. level  The maximum level of compression that will be supported. prm  Additional configuation parameter, unused as of now qse  The generic datagram context

int QDF_acdCtxSizeof (  unsigned int  level, void *  prm )

Returns the size, in bytes of the ACD decoding context needed to support the specified compression level. Returns: The size, in bytes, of the ACD decoding context Parameters: level  The maximum level of compression that needs to be supported prm  Additional configuation parameter, unused as of now

int QDF_acdCtxUpdate (  QDF_acdCtx *  ctx, QFR_fileCtx *  qfr, const CDF_acdBdy *  bdy )

Updates the ACD context from the datagram contribution. Return values: 0,Success  0x80000001,Pedestal  file error, not found 0x80000002,Pedestal  file error, checksum does not match Parameters: ctx  The context to update qfr  The file translation context bdy  The update information

QDF_acdEvt* QDF_acdEvtConstruct (  QDF_acdEvt *  evt, unsigned int  level, void *  prm, QDF_exc *  exc, QDF_esbEvt *  esb, QDF_gemEvt *  gem )

Constructs (initializes) the specified ACD event structure. Returns: Pointer to the context structure to construct Parameters: evt  The ACD event structure to construct. level  The maximum level of compression that will be supported. prm  Additional configuation parameter, unused as of now exc  The exception handling context. esb  Pointer to the Event Summary Data for this event gem  Pointer to the GEM data for this event

int QDF_acdEvtSizeof (  unsigned int  level, void *  prm )

Returns the size, in bytes of QDF_acd event needed to support the specified compression level. Returns: The size, in bytes, of the ACD event Parameters: level  The maximum level of compression that needs to be supported prm  Additional configuation parameter, unused as of now

BFU QDF_acdPedDecode (  QDF_acdCtx *  ctx, QDF_acdEvt *  evt, const unsigned int *  src, const unsigned int  max, BFU  bfu )

Decodes the ACD. Returns: The updated bit position and current deblocked 32-bit buffer Parameters: ctx  The compressed data decoding context evt  The ACD event block to fill in src  The data source, i.e. the bit stream max  The maximum bit position bfu  The current bit position and temporary buffer This routine is a simple dispatcher, extracting the formatting style, then dispatching to the appropriate decoding routine.

BFU QDF_acdStdDecode (  QDF_acdCtx *  ctx, QDF_acdEvt *  evt, const unsigned int *  src, const unsigned int  max, BFU  bfu )

Decodes the ACD. Returns: The updated bit position and current deblocked 32-bit buffer Parameters: ctx  The compressed data decoding context evt  The ACD event block to fill in src  The data source, i.e. the bit stream max  The maximum bit position bfu  The current bit position and temporary buffer
