int
lowdown_file(const struct lowdown_opts *opts, FILE *in, char **ret, size_t *retsz, struct lowdown_metaq *metaq);

Parses a lowdown(5) file stream in into an output buffer ret of size retsz according to configuration opts. The output format is specified by opts->type. If LOWDOWN_METADATA is set in opts->feat and metaq is not NULL, metaq is filled with metadata rendered in the given output format.

On success, the caller is responsible for freeing ret and metaq.

Returns zero on failure, non-zero on success. On failure, the values pointed to by res and rsz are undefined.

The following parses standard input into a standalone HTML5 document. It enables footnotes, autolinks, tables, superscript, strikethrough, fenced codeblocks, commonmark, definition lists, extended image attributes, and metadata processing. The output passes through raw HTML and has smart typography.
