void * RIFF::Chunk::LoadChunkData | ( | ) |
Load chunk body into RAM.
Loads the whole chunk body into memory. You can modify the data in RAM and save the data by calling File::Save() afterwards.
Caution: the buffer pointer will be invalidated once File::Save() was called. You have to call LoadChunkData() again to get a new, valid pointer whenever File::Save() was called.
You can call LoadChunkData() again if you previously scheduled to enlarge this chunk with a Resize() call. In that case the buffer will be enlarged to the new, scheduled chunk size and you can already place the new chunk data to the buffer and finally call File::Save() to enlarge the chunk physically and write the new data in one rush. This approach is definitely recommended if you have to enlarge and write new data to a lot of chunks.

void RIFF::Chunk::Resize | ( | int | iNewSize | ) |
Resize chunk.
Resizes this chunk's body, that is the actual size of data possible to be written to this chunk. This call will return immediately and just schedule the resize operation. You should call File::Save() to actually perform the resize operation(s) "physically" to the file. As this can take a while on large files, it is recommended to call Resize() first on all chunks which have to be resized and finally to call File::Save() to perform all those resize operations in one rush.
Caution: You cannot directly write to enlarged chunks before calling File::Save() as this might exceed the current chunk's body boundary!
