parsechunk

void parsechunk(InStream prf)

Descend into the RIFF file hierarchy, recursively parsing chunks.

Parameters:

prf - An input stream of RIFF data, positioned just prior to a chunk.

parsechunk

void parsechunk(InStream prf,
                FourByteConstant fcc)

Descend into the RIFF file hierarchy, recursively parsing chunks.

Parameters:

prf - An input stream of RIFF data, where fcc has already been read.

fcc - The first four bytes of the current RIFF chunk.

parsechunk

void parsechunk(InStream prf,
                IOChunk chunk)

Parse Chunk and then descend recursively into the RIFF file hierarchy.

Parameters:

prf - An input stream of RIFF data.

chunk - The enclosing chunk, to be printed.
