   Hello!

   In file 'xmlrpc.php' we can find out useful functions.
   Also here: link

   What I want to do is to obtain (complete) list of post ID's for given category Name or ID i.e. getPosts(4)

   I have found two functions in xmlrmpc.php which we can use:
   a) mw_getCategories and b) mw_getRecentPosts

   For a) myBlog.getCategories() (I'm using C#)
   We receive struct array of Categories which contains 'Category Id' , 'Name' etc.

   1st question. How I can add to those structs, array of posts id's which are in this category ?
   (I can get post giving the post id, that's why I want to obtain posts id's of specific category)

   For b) myBlog.getRecentPosts(20) where 20 is the numer of posts to receive

   2nd question. How I can change this function to give category name/id and return all posts in that category id/name ?

   Any ideas? Could someone help me with this?

   Best Regards,
   Matt

   Example in files:

   function mw_getCategories($args) {
   
   		$this->escape($args);
   
   		$blog_ID     = (int) $args[0];
   		$username  = $args[1];
   		$password   = $args[2];
   
   		if ( !$user = $this->login($username, $password) ) {
   			return $this->error;
   		}
   
   		if( !current_user_can( 'edit_posts' ) )
   			return new IXR_Error( 401, __( 'Sorry, you must be able to edit posts on this blog in order to view categories.' ) );
   
   		do_action('xmlrpc_call', 'metaWeblog.getCategories');
   
   		$categories_struct = array();
   
   		if ( $cats = get_categories('get=all') ) {
   			foreach ( $cats as $cat ) {
   				$struct['categoryId'] = $cat->term_id;
   				$struct['parentId'] = $cat->parent;

   add here i.e $struct['AllPosts'] which will be contains all posts ID's in this category.

   $struct['description'] = $cat->name;
   				$struct['categoryDescription'] = $cat->description;
   				$struct['categoryName'] = $cat->name;
   				$struct['htmlUrl'] = esc_html(get_category_link($cat->term_id));
   				$struct['rssUrl'] = esc_html(get_category_feed_link($cat->term_id, 'rss2'));
   
   				$categories_struct[] = $struct;
   			}
   		}
   
   		return $categories_struct;
   	}

   function mw_getRecentPosts($args) {
   
   		$this->escape($args);
   
   		$blog_ID     = (int) $args[0];
   		$username  = $args[1];
   		$password   = $args[2];
   		$num_posts   = (int) $args[3];
   
   		if ( !$user = $this->login($username, $password) ) {
   			return $this->error;
   		}
   
   		do_action('xmlrpc_call', 'metaWeblog.getRecentPosts');
   
   		$posts_list = wp_get_recent_posts($num_posts);

   change num_posts to category_id and recive all posts in that category

   if (!$posts_list) {
   			return array( );
   		}
   
   		foreach ($posts_list as $entry) {
   			if( !current_user_can( 'edit_post', $entry['ID'] ) )
   				continue;
   
   			$post_date = mysql2date('Ymd\TH:i:s', $entry['post_date'], false);
   			$post_date_gmt = mysql2date('Ymd\TH:i:s', $entry['post_date_gmt'], false);
   
   			// For drafts use the GMT version of the date
   			if ( $entry['post_status'] == 'draft' ) {
   				$post_date_gmt = get_gmt_from_date( mysql2date( 'Y-m-d H:i:s', $entry['post_date'] ), 'Ymd\TH:i:s' );
   			}
   
   			$categories = array();
   			$catids = wp_get_post_categories($entry['ID']);
   			foreach($catids as $catid) {
   				$categories[] = get_cat_name($catid);
   			}
   
   			$tagnames = array();
   			$tags = wp_get_post_tags( $entry['ID'] );
   			if ( !empty( $tags ) ) {
   				foreach ( $tags as $tag ) {
   					$tagnames[] = $tag->name;
   				}
   				$tagnames = implode( ', ', $tagnames );
   			} else {
   				$tagnames = '';
   			}
   
   			$post = get_extended($entry['post_content']);
   			$link = post_permalink($entry['ID']);
   
   			// Get the post author info.
   			$author = get_userdata($entry['post_author']);
   
   			$allow_comments = ('open' == $entry['comment_status']) ? 1 : 0;
   			$allow_pings = ('open' == $entry['ping_status']) ? 1 : 0;
   
   			// Consider future posts as published
   			if( $entry['post_status'] === 'future' ) {
   				$entry['post_status'] = 'publish';
   			}
   
   			$struct[] = array(
   				'dateCreated' => new IXR_Date($post_date),

   		}
   
   		$recent_posts = array();
   		for ($j=0; $j<count($struct); $j++) {
   			array_push($recent_posts, $struct[$j]);
   		}
   
   		return $recent_posts;
