wp_update_plugin( $plugin, $feedback = '' )

This function has been deprecated. Use Plugin_Upgrader() instead.

This was once used to kick-off the Plugin Updater.

Description

Deprecated in favor of instantating a Plugin_Upgrader instance directly, and calling the ‘upgrade’ method. Unused since 2.8.0.
