Description:

[ CCode ( type_id = "g_seekable_get_type ()" ) ]
public interface Seekable : Object

`GSeekable` is implemented by streams (implementations of [class@Gio.

InputStream] or [class@Gio.OutputStream]) that support seeking.

Seekable streams largely fall into two categories: resizable and fixed-size.

`GSeekable` on fixed-sized streams is approximately the same as POSIX [`lseek()`](man:lseek(2)) on a block device (for example: attempting to seek past the end of the device is an error). Fixed streams typically cannot be truncated.

`GSeekable` on resizable streams is approximately the same as POSIX [`lseek()`](man:lseek(2)) on a normal file. Seeking past the end and writing data will usually cause the stream to resize by introducing zero bytes.

Methods:

public abstract bool can_seek ()
Tests if the stream supports the Seekable .
public abstract bool can_truncate ()
Tests if the length of the stream can be adjusted with truncate.
public abstract bool seek (int64 offset, SeekType type, Cancellable? cancellable = null) throws Error
Seeks in the stream by the given offset, modified by type.
public abstract int64 tell ()
Tells the current position within the stream.
public abstract bool truncate (int64 offset, Cancellable? cancellable = null) throws Error
Sets the length of the stream to offset.
