DESCRIPTION

     The markdown format supported in this implementation includes Pandoc-style header and inline
     <style> blocks, and the standard markdown(3) functions do not provide access to the data
     provided by either of those extensions.  These functions give you access to that data, plus
     they provide a finer-grained way of converting Markdown documents into HTML.

     Given a MMIOT* generated by mkd_in() or mkd_string(), mkd_compile() compiles the document
     into <style>, Pandoc, and html sections.

     Once compiled, the document can be examined and written by the mkd_css(), mkd_document(),
     mkd_generatecss(), mkd_generatehtml(), mkd_generatetoc(), mkd_toc(), mkd_xhtmlpage(),
     mkd_doc_title(), mkd_doc_author(), and mkd_doc_date() functions.

     mkd_css() allocates a string and populates it with any <style> sections provided in the
     document, mkd_generatecss() writes any <style> sections to the output, mkd_document() points
     text to the text of the document and returns the size of the document, mkd_generatehtml()
     writes the rest of the document to the output, and mkd_doc_title(), mkd_doc_author(),
     mkd_doc_date() are used to read the contents of a Pandoc header, if any.

     mkd_xhtmlpage() writes a xhtml page containing the document.  The regular set of flags can
     be passed.

     mkd_toc() writes a document outline, in the form of a collection of nested lists with links
     to each header in the document, into a string allocated with malloc(), and returns the size.

     mkd_generatetoc() is like mkd_toc(), except that it writes the document outline to the given
     FILE* argument.

     mkd_cleanup() deletes a MMIOT* after processing is done.

     mkd_compile() accepts the same flags that markdown() and mkd_string() do;
     MKD_NOIMAGE          Do not process `![]' and remove <img> tags from the output.
     MKD_NOLINKS          Do not process `[]' and remove <a> tags from the output.
     MKD_NOPANTS          Do not do Smartypants-style mangling of quotes, dashes, or ellipses.
     MKD_TAGTEXT          Process the input as if you were inside a html tag.  This means that no
                          html tags will be generated, and mkd_compile() will attempt to escape
                          anything that might terribly confuse a web browser.
     MKD_NO_EXT           Do not process any markdown pseudo-protocols when handing [][] links.
     MKD_NOHEADER         Do not attempt to parse any Pandoc-style headers.
     MKD_TOC              Label all headers for use with the mkd_generatetoc() function.
     MKD_1_COMPAT         MarkdownTest_1.0 compatibility flag; trim trailing spaces from the
                          first line of code blocks and disable implicit reference links.
     MKD_NOSTRIKETHROUGH  Disable strikethrough support.

RETURN VALUES

     The function mkd_compile() returns 1 in the case of success, or 0 if the document is already
     compiled.  The function mkd_generatecss() returns the number of bytes written in the case of
     success, or EOF if an error occurred.  The function mkd_generatehtml() returns 0 on success,
     -1 on failure.

BUGS

     Error handling is minimal at best.
