Description GFileInputStream 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(). To find out if a file input stream supports seeking, use g_seekable_stream_can_seek(). To position a file input stream, use g_seekable_seek().
