GLib.IOChannel.new_file
Description: Reference for GLib.IOChannel.new_file

### Function

# GLib IOChannelnew_file

#### Declaration

    GIOChannel*
    g_io_channel_new_file (
      const gchar* filename,
      const gchar* mode,
      GError** error
    )

#### Description

Open a file `filename` as a `GIOChannel` using mode `mode`. This channel will be closed when the last reference to it is dropped, so there is no need to call `g_io_channel_close()` (though doing so will not cause problems, as long as no attempt is made to access the channel after it is closed).

#### Parameters

`filename`

  Type: `const gchar*`

  A string containing the name of a file.

  The data is owned by the caller of the function.
  The value is a file system path, using the OS encoding.

`mode`

  Type: `const gchar*`

  One of “r”, “w”, “a”, “r+”, “w+”, “a+”. These have the same meaning as in `fopen()`

  The data is owned by the caller of the function.
  The value is a NUL terminated UTF-8 string.

`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 function 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: `GIOChannel`

A `GIOChannel` on success, `NULL` on failure.

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