gSeekableTruncate {RGtk2} | R Documentation

## gSeekableTruncate

### Description

Truncates a stream with a given `offset`.

### Usage

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

### Arguments

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

### Details

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.

### Value

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.
