void
lowdown_nroff_free(void *arg);

Frees the roff renderer created with lowdown_nroff_new(3). If arg is NULL, the function does nothing.

The following parses b of length bsz and outputs in groff_ms(7) format.

struct lowdown_buf *out;
struct lowdown_doc *doc;
struct lowdown_node *n;
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 ((out = lowdown_buf_new(256)) == NULL)
	err(1, NULL);
if ((rndr = lowdown_nroff_new(NULL)) == NULL)
	err(1, NULL);
if (!lowdown_nroff_rndr(out, rndr, n))
	err(1, NULL);

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

lowdown_nroff_free(rndr);
lowdown_buf_free(out);
lowdown_node_free(n);
lowdown_doc_free(doc);

lowdown(3), lowdown_nroff_new(3)

This uses both the original troff man macros for Version 7 AT&T UNIX, defined in man(7), and the man-ext groff extensions. Both are implemented in mandoc.

The troff ms macros are defined in groff_ms(7), with the mspdf groff extensions described in "Portable Document Format Publishing with GNU Troff" by Keith Marshall. Neither are implemented in mandoc.
