int readIntoSync(
List<int> buffer,
[int start,
int end]
)

Synchronously reads into an existing List<int> from the file. If start is present, the bytes will be filled into buffer from at index start, otherwise index 0. If end is present, the end - start bytes will be read into buffer, otherwise up to buffer.length. If end == start nothing happends.

Throws a FileSystemException if the operation fails.
