Gio.Seekable.seek

### Method

# Gio Seekableseek

#### Declaration

    gboolean
    g_seekable_seek (
      GSeekable* seekable,
      goffset offset,
      GSeekType type,
      GCancellable* cancellable,
      GError** error
    )

#### Description

Seeks in the stream by the given `offset`, modified by `type`.

Attempting to seek past the end of the stream will have different results depending on if the stream is fixed-sized or resizable. If the stream is resizable then seeking past the end and then writing will result in zeros filling the empty space. Seeking past the end of a resizable stream and reading will result in EOF. Seeking past the end of a fixed-sized stream will fail.

Any operation that would result in a negative offset will fail.

If `cancellable` is not `NULL`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error `G_IO_ERROR_CANCELLED` will be returned.

#### Parameters

`offset`

  Type: `goffset`

  A #goffset.

`type`

  Type: `GSeekType`

  A `GSeekType`.

`cancellable`

  Type: `GCancellable`

  Optional `GCancellable` object, `NULL` to ignore.

  The argument can be `NULL`.
  The data is owned by the caller of the method.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the method if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `gboolean`

`TRUE` if successful. If an error has occurred, this function will return `FALSE` and set `error` appropriately if present.
