Method

GioMountguess_content_type

Declaration

void
g_mount_guess_content_type (
  GMount* mount,
  gboolean force_rescan,
  GCancellable* cancellable,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description

Tries to guess the type of content stored on mount. Returns one or more textual identifiers of well-known content types (typically prefixed with “x-content/”), e.g. x-content/image-dcf for camera memory cards. See the shared-mime-info specification for more on x-content types.

This is an asynchronous operation (see g_mount_guess_content_type_sync() for the synchronous version), and is finished by calling g_mount_guess_content_type_finish() with the mount and GAsyncResult data returned in the callback.
