  GDataInputStream* stream,
  GAsyncResult* result,

  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.

Type: GAsyncResult

The GAsyncResult that was provided to the callback.

The data is owned by the caller of the function.

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.

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 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: 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.
