+ * of them. It is then noted that while this function does not work on posts, it
+ * does not mean that it won't work on posts. It is recommended that you know
+ * what context you wish to retrieve the children of.
+ *
+ * Attachments may also be made the child of a post, so if that is an accurate
+ * statement (which needs to be verified), it would then be possible to get

+ * example of what is possible.
+ *
+ * The arguments listed as defaults are for this function and also of the
+ * {@link get_posts()} function. The arguments are combined with the
+ * get_children defaults and are then passed to the {@link get_posts()}
+ * function, which accepts additional arguments. You can replace the defaults in
+ * this function, listed below and the additional arguments listed in the
+ * {@link get_posts()} function.
+ *
+ * The 'post_parent' is the most important argument and important attention
+ * needs to be paid to the $args parameter. If you pass either an object or an
+ * integer (number), then just the 'post_parent' is grabbed and everything else
+ * is lost. If you don't specify any arguments, then it is assumed that you are
+ * in The Loop and the post parent will be grabbed for from the current post.
+ *
+ * The 'post_parent' argument is the ID to get the children. The 'numberposts'
+ * is the amount of posts to retrieve that has a default of '-1', which is
+ * used to get all of the posts. Giving a number higher than 0 will only
+ * retrieve that amount of posts.
+ *
+ * The 'post_type' and 'post_status' arguments can be used to choose what
+ * criteria of posts to retrieve. The 'post_type' can be anything, but WordPress
+ * post types are 'post', 'pages', and 'attachments'. The 'post_status'
+ * argument will accept any post status within the write administration panels.
+ *
+ * @see get_posts() Has additional arguments that can be replaced.
+ * @internal Claims made in the long description might be inaccurate.
+ *
+ * @since 2.0.0
+ *
+ * @param mixed $args Optional. User defined arguments for replacing the defaults.
+ * @param string $output Optional. Constant for return type, either OBJECT (default), ARRAY_A, ARRAY_N.
