Marks a function argument as deprecated and inform when it has been used.
This function is to be used whenever a deprecated function argument is used. Before this function is called, the argument must be checked for whether it was used by comparing it to its default value or evaluating whether it is empty. For example: if ( ! empty( $deprecated ) ) { _deprecated_argument( FUNCTION, '3.0.0' ); } There is a {@see 'deprecated_argument_run'} hook that will be called that can be used to get the backtrace up to what file and function used the deprecated argument. The current behavior is to trigger a user error if WP_DEBUG is true.Related Functions: rest_handle_deprecated_argument, _deprecated_function, _deprecated_file, _deprecated_class, _deprecated_hook
