I'd like to place a directive in my theme's functions.php file which appends a classname to the wordpress body tag. Is there a built-in API method for this?
For example, my body tag code is...
<body <?php if(function_exists("body_class") && !is_404()){body_class();} else echo 'class="page default"'?>>
And it results in the following being written to the body tag (depending on the context in which the page is presented (page, post, logged-in, etc)
<body class="home blog logged-in">
Depending on the child theme I'm using at the time, I want it to be...
<body class="home blog logged-in mychildthemename">
