LOWDOWN_NROFF_FREE(3)      Library Functions Manual      LOWDOWN_NROFF_FREE(3)

NAME
     lowdown_nroff_free - free a Markdown roff renderer

LIBRARY
     library "liblowdown"

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

     void
     lowdown_nroff_free(void *arg);

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

EXAMPLES
     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);

     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.
