markdown - Man Page

Markdown (libmarkdown, -lmarkdown)

#include <mkdio.h>

MMIOT
*mkd_in(FILE *input, int flags);

MMIOT
*mkd_string(char *string, int size, int flags);

int
markdown(MMIOT *doc, FILE *output, int flags);

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:
