Virtual Method
GioMountguess_content_type_sync
since: 2.18
Declaration [src]
gchar**
guess_content_type_sync (
  GMount* mount,
  gboolean force_rescan,
  GCancellable* cancellable,
  GError** error
)
Description [src]
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 a synchronous operation and as such may block doing IO; see g_mount_guess_content_type() for the asynchronous version.
Available since: 2.18
Parameters
- force_rescan

            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 aNULLGError*.The argument will be left initialized to NULLby the virtual function 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.
