17 * Copy the provided stream to memory allocated by storage.
18 * Used by SkImageDecoder_libbmp and SkImageDecoder_libico.

20 * enough to hold the entire stream. Upon successful return,

23 * @param stream SkStream to be copied into storage.
24 * @return size_t Total number of bytes in the SkStream, which is also the
25 * number of bytes pointed to by storage->get(). Returns 0 on failure.

31 * @param stream SkStream to be copied into data.
32 * @return SkData* The resulting SkData after the copy. This data
33 * will have a ref count of one upon return and belongs to the
