gFileAppendTo {RGtk2} | R Documentation

## gFileAppendTo

### Description

Gets an output stream for appending data to the file. If the file doesn't already exist it is created.

### Usage

    gFileAppendTo(object, flags = "G_FILE_CREATE_NONE", cancellable = NULL,
        .errwarn = TRUE)

### Arguments

``object`` | input `GFile`.
``flags`` | a set of `GFileCreateFlags`.
``cancellable`` | optional `GCancellable` object, `NULL` to ignore.
`.errwarn` | Whether to issue a warning on error or fail silently

### Details

By default files created are generally readable by everyone, but if you pass `G_FILE_CREATE_PRIVATE` in `flags` the file will be made readable only to the current user, to the level that is supported on the target filesystem.

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.

Some file systems don't allow all file names, and may return an `G_IO_ERROR_INVALID_FILENAME` error. If the file is a directory the `G_IO_ERROR_IS_DIRECTORY` error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

### Value

A list containing the following elements:

`retval` | [`GFileOutputStream`] a `GFileOutputStream`, or `NULL` on error.
``error`` | a `GError`, or `NULL`
