Member Function Documentation

◆ Ascend()

HRESULT GrayLib::cRIFFReader::Ascend ( cRIFFHeadX *  pChunk)

Seek back to my parent chunk. fill in the data size if the chunk required it. (writing) like "::mmioAscend( m_hmmFile, pInfo, 0 ));"

◆ DescendChunk()

HRESULT GrayLib::cRIFFReader::DescendChunk ( cRIFFHeadX *  pChunk,
const cRIFFHeadX *  pChunkList,
FOURCC  nTypeChunk = FOURCC_0 
)

find/seek a particular chunk type.

Note
pChunkList may be nullptr Expect Ascend() to be called for pChunk nTypeChunk = just find the next chunk.

◆ DescendLIST()

HRESULT GrayLib::cRIFFReader::DescendLIST ( cRIFFHeadX *  pChunk,
const cRIFFHeadX *  pChunkList,
FOURCC  nTypeList 
)

find/seek a particular LIST type inside a RIFF or other LIST. Expect Ascend() to be called for pChunk

◆ DescendRIFF()

HRESULT GrayLib::cRIFFReader::DescendRIFF ( cRIFFHeadX *  pChunkList,
FOURCC  nTypeList 
)

from the current pos. find the RIFF chunk Expect Ascend() to be called for pChunk
