1	gSeekableTruncate(object, offset, cancellable = NULL, .errwarn = TRUE)

`object`	a `GSeekable`.
`offset`	a `numeric`.
`cancellable`	optional `GCancellable` object, `NULL` to ignore.
`.errwarn`	Whether to issue a warning on error or fail silently

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. If an operation was partially finished when the operation was cancelled the partial result will be returned, without an error.

A list containing the following elements:

`retval`	[logical] `TRUE` if successful. If an error has occurred, this function will return `FALSE` and set `error` appropriately if present.
`error`	a `GError` location to store the error occuring, or `NULL` to ignore.
