SilcSnprintfRender

SYNOPSIS

    typedef char *(*SilcSnprintfRender)(void *data);

DESCRIPTION

Snprintf rendering function. This function can be used with '%@' formatting character. The `data' is rendered into a string and allocated string is returned. If NULL is returned the rendering is skipped and ignored. If the returned string does not fit to the destination buffer it may be truncated.

EXAMPLE

    char *id_render(void *data)
    {
      ...render...
      return id_string;
    }

    // Call id_render function to render the 'client_id'.
    silc_snprintf(buf, sizeof(buf), "Client ID %@", id_render, client_id);
