lowdown_doc_parse — parse a Markdown document into an AST

       Parse a lowdown(5) document input of length inputsz into an AST with the parser doc.  The maxn  argument,
       if  not  NULL,  is  set  to  one greater than the highest node identifier.  Its value is undefined if the
       function returns NULL.

       If metaq is not NULL, it is  filled  in  with  document  metadata  (if  any).   Metadata  key  names  are
       canonicalised and duplicate names are ignored.  The results should be freed with lowdown_metaq_free(3).

       This function may be invoked multiple times with a single doc and different input.

       The following parses b of length bsz.  It first  allocates  the  parser,  then  the  document,  then  the
       renderer  (HTML  is  used in this case).  Then it passes output to the renderer, prints it, and cleans up
       resources.  On any memory errors, it exits with err(3).

             struct lowdown_doc *doc;
             struct lowdown_node *n;
             struct lowdown_buf *ob;
             void *rndr;

             if ((doc = lowdown_doc_new(NULL)) == NULL)
                     err(1, NULL);
             if ((n = lowdown_doc_parse(doc, NULL, b, bsz, NULL)) == NULL)
                     err(1, NULL);
             if ((rndr = lowdown_html_new(NULL)) == NULL)
                     err(1, NULL);
             if ((ob = lowdown_buf_new(1024)) == NULL)
                     err(1, NULL);
             if (!lowdown_html_rndr(ob, rndr, n))
                     err(1, NULL);

             fwrite(stdout, 1, ob->size, ob->data);

             lowdown_buf_free(ob);
             lowdown_html_rndr_free(rndr);
             lowdown_node_free(n);
             lowdown_doc_free(doc);

       lowdown_doc_parse — parse a Markdown document into an AST

       Returns  the root of the parse tree or NULL on memory allocation failure.  If not NULL, the returned node
       is always of type LOWDOWN_ROOT.
