/**
* Retrieve all children of the post parent ID.
*
* Normally, without any enhancements, the children would apply to pages. In the
* context of the inner workings of WordPress, pages, posts, and attachments
* 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
* version 2.5, so this is most likely unaccurate, but serves generally as an
* 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.
* @return array|bool False on failure and the type will be determined by $output parameter.
