Cue-Points Chunk

The <cue-ck> cue-points chunk identifies a series of positions in the waveform data stream. The <cue-ck> is defined as follows:

<cue-ck>    cue(    <ulCuePoints:ULONG> /* Count of cue points */
                     <cue-point>... )      /* Cue-point table */
<cue-point>  struct {
                    ULONG  ulName;
                    ULONG  ulPosition;
                    FOURCC fccChunk;
                    ULONG  ulChunkStart;
                    ULONG  ulBlockStart;
                    ULONG  ulSampleOffset;
                 }

The <cue-point> fields are as follows:

Field

Description
ulName
Specifies the cue point name. Each <cue-point> record must have a unique ulName field.
ulPosition
Specifies the sample position of the cue point. This is the sequential sample number within the play order. See Playlist Chunk later in this document, for a discussion of the play order.
fccChunk
Specifies the name or chunk ID of the chunk containing the cue point.
ulChunkStart
Specifies the file position of the start of the chunk containing the cue point. This is a byte offset relative to the start of the data section of the 'wavl' LIST chunk.
ulBlockStart
Specifies the file position of the start of the block containing the position. This is a byte offset relative to the start of the data section of the 'wavl' LIST chunk.
ulSampleOffset
Specifies the sample offset of the cue point relative to the start of the block.
