Virtual Method



query_info (
  GFileInputStream* stream,
  const char* attributes,
  GCancellable* cancellable,
  GError** error


Queries a file input stream the given attributes. This function blocks while querying the stream. For the asynchronous (non-blocking) version of this function, see g_file_input_stream_query_info_async(). While the stream is blocked, the stream will set the pending flag internally, and any other operations on the stream will fail with G_IO_ERROR_PENDING.

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

Optional GCancellable object, NULL to ignore.

The argument can be NULL.

Type: GError **

The return location for a recoverable error.
