g_data_input_stream_read_line_finish (
  GDataInputStream* stream,
  GAsyncResult* result,
  gsize* length,
  GError** error


Finish an asynchronous call started by g_data_input_stream_read_line_async(). Note the warning about string encoding in g_data_input_stream_read_line() applies here as well.

Available since:2.20


result GAsyncResult

The GAsyncResult that was provided to the callback.

 The data is owned by the caller of the function.
length 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 GError **
  The return location for a GError*, or NULL.

Return value

Returns: An array of guint8

a NUL-terminated byte array with the line that was read in (without the newlines). Set length to a #gsize to get the length of the read line. On an error, it will return NULL and error will be set. If there’s no content to read, it will still return NULL, but error won’t be set.

 The array is NULL-terminated.
 The caller of the method takes ownership of the data, and is responsible for freeing it.
 The return value can be NULL.
