Gio.Mount::guess_content_type_sync

function vfunc_guess_content_type_sync(force_rescan: Boolean, cancellable: Gio.Cancellable): Array(String) {
}
  

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](http://www.freedesktop.org/wiki/Specifications/shared-mime-info-spec) specification for more on x-content types.

This is an synchronous operation and as such may block doing IO; see Gio.Mount.prototype.guess_content_type for the asynchronous version.
