### Method

# Gio DataInputStream read_until_finish

deprecated: 2.56 since: 2.20

#### Declaration

    char*
    g_data_input_stream_read_until_finish (
      GDataInputStream* stream,
      GAsyncResult* result,
      gsize* length,
      GError** error
    )

#### Description

Finish an asynchronous call started by g_data_input_stream_read_until_async().

Available since: 2.20

Deprecated since: 2.56

Use `g_data_input_stream_read_upto_finish()` instead, which has more consistent behaviour regarding the stop character.

#### Parameters

`result`

  Type: `GAsyncResult`

  The `GAsyncResult` that was provided to the callback.

  The data is owned by the caller of the method.

`length`

  Type: `gsize*`

  A #gsize to get the length of the data read in.

  The argument will be set by the function.
  The argument can be `NULL`.

`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: `char*`

A string with the data that was read before encountering any of the stop characters. Set `length` to a #gsize to get the length of the string. This function will return `NULL` on an error.

The caller of the method takes ownership of the data, and is responsible for freeing it.
The value is a NUL terminated UTF-8 string.
