static void LwoSurfaceBlockOpacity::init_type | ( | ) | [inline, static] |
This function is declared non-inline to work around a compiler bug in g++ 2.96.
Making it inline seems to cause problems in the optimizer.
Reimplemented from LwoChunk.

bool LwoSurfaceBlockOpacity::read_iff | ( | IffInputFile * | in, |
size_t | stop_at | ||
) | [virtual] |
Reads the data of the chunk in from the given input file, if possible.
The ID and length of the chunk have already been read. stop_at is the byte position of the file to stop at (based on the current position at in->get_bytes_read()). Returns true on success, false otherwise.
Implements IffChunk.
