lowdown_gemini_free — free a Markdown gemini renderer

library “liblowdown”

#include <sys/queue.h>
#include <stdio.h>
#include <lowdown.h>

void
lowdown_gemini_free(void *arg);

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

The following assumes the the string buf of length bsz consists of Markdown content.

struct lowdown_buf *out;
struct lowdown_doc *doc;
struct lowdown_node *n;
void *rndr;

if (setlocale(LC_CTYPE, "en_US.UTF-8") == NULL)
  err(1, NULL);

if ((doc = lowdown_doc_new(NULL)) == NULL)
  err(1, NULL);
if ((n = lowdown_doc_parse(doc, NULL, buf, bsz)) == NULL)
  err(1, NULL);
if ((out = lowdown_buf_new(256)) == NULL)
  err(1, NULL);
if ((rndr = lowdown_gemini_new(NULL)) == NULL)
  err(1, NULL);
if (!lowdown_gemini_rndr(out, NULL, rndr, n))
  err(1, NULL);

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

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