Gio.File.create

### Method

# Gio Filecreate

#### Declaration [src]

    GFileOutputStream*
    g_file_create (
      GFile* file,
      GFileCreateFlags flags,
      GCancellable* cancellable,
      GError** error
    )

#### Description [src]

Creates a new file and returns an output stream for writing to it. The file must not already exist.

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.

If a file or directory with this name already exists the `G_IO_ERROR_EXISTS` error will be returned. Some file systems don’t allow all file names, and may return an `G_IO_ERROR_INVALID_FILENAME` error, and if the name is to long `G_IO_ERROR_FILENAME_TOO_LONG` will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

#### Parameters

`flags`

  Type: `GFileCreateFlags`

  A set of `GFileCreateFlags`.

`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: `GFileOutputStream`

A `GFileOutputStream` for the newly created file, or `NULL` on error. Free the returned object with g_object_unref().

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
