Description
These functions convert Markdown documents and strings into HTML. markdown() processes an entire document, while mkd_text() processes a single string.
To process a file, you pass a FILE* to mkd_in(), and if it returns a nonzero value you pass that in to markdown(), which then writes the converted document to the specified FILE*. If your input has already been written into a string (generated input or a file opened with mmap(2)) you can feed that string to mkd_string() and pass its return value to markdown.()
Markdown() accepts the following flag values (or-ed together if needed) to restrict how it processes input:
MKD_NOLINKS' Don't do link processing, block <a>tags.MKD_NOIMAGE' Don't do image processing, block <img>.
MKD_NOPANTS' Don't run smartypants().
MKD_NOHTML' Don't allow raw html through AT ALL
MKD_STRICT' Disable superscript and relaxed emphasis.
MKD_TAGTEXT' Process text inside an html tag; no <em>, no <bold>, no html or [] expansion.
MKD_NO_EXT' Don't allow pseudo-protocols.
MKD_CDATA' Generate code for xml ![CDATA[...]].
MKD_NOSUPERSCRIPT' Don't generate superscripts. Emphasis happens _everywhere_
MKD_NOTABLES' Disallow tables.

Bugs
Error handling is minimal at best.
The MMIOT created by mkd_string() is deleted by the markdown function.
