 * share the same table, so therefore the functionality could apply to any one

 * 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

 * all of the attachments for a post. Attachments have since changed since

 * example of what is possible.

 *

 * The arguments listed as defaults are for this function and also of the

 *

 * 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.

 *

 * @since 2.0.0

 *

 * @see get_posts()

 * @todo Check validity of description.

 *

 * @param mixed  $args   Optional. User defined arguments for replacing the defaults. Default empty.

 * @return array Array of children, where the type of each element is determined by $output parameter.
