C++ (Cpp) VA_OPEN Examples

Example #1

int
asprintf (char **buf, const char *fmt, ...)
{
  int status;
  VA_OPEN (ap, fmt);
  VA_FIXEDARG (ap, char **, buf);
  VA_FIXEDARG (ap, const char *, fmt);
  status = vasprintf (buf, fmt, ap);
  VA_CLOSE (ap);
  return status;
}

Example #2

File: _doprnt.c Project: 0mp/freebsd

static int
checkit (const char* format, ...)
{
  int result;
  VA_OPEN (args, format);
  VA_FIXEDARG (args, char *, format);

  result = _doprnt (format, args, stdout);
  VA_CLOSE (args);

  return result;
}

Example #3

int
snprintf (char *s, size_t n, const char *format, ...)
{
  int result;
  VA_OPEN (ap, format);
  VA_FIXEDARG (ap, char *, s);
  VA_FIXEDARG (ap, size_t, n);
  VA_FIXEDARG (ap, const char *, format);
  result = vsnprintf (s, n, format, ap);
  VA_CLOSE (ap);
  return result;
}
