result GAsyncResult

The GAsyncResult that was provided to the callback.

 The data is owned by the caller of the function.

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 **

Return value

Returns: char*

A string 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. For UTF-8 conversion errors, the set error domain is G_CONVERT_ERROR. If there’s no content to read, it will still return NULL, but error won’t be set.

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