There is no IO exception in case of ByteArrayInputStream class methods. Methods of this class can be called even after closing the Stream, there is no effect of it on the class methods. The class view is as follows:
WebGFileInputStream provides input streams that take their content from a file. GFileInputStream implements GSeekable, which allows the input stream to jump to arbitrary positions in the file, provided the filesystem of the file allows it. To find the position of a file input stream, use g_seekable_tell ().
