Member Function Documentation

size_t ZStreamR_LZWEncodeNoPatent::Imp_CountReadable (  )  [virtual]

Returns the number of bytes guaranteed to be readable without blocking.

If the stream does not or cannot know this information it should return zero. A zero return thus does not mean no data is available, simply that a subsequent Read or Skip may block indefinitely.

Reimplemented from ZStreamR.
