Here is the caller graph for this function:

◆ GNUNET_asprintf()

int GNUNET_asprintf	(	char **	buf,
		const char *	format,
			...
	)

Like asprintf(), just portable.

Parameters

buf	set to a buffer of sufficient size (allocated, caller must free)
format	format string (see printf(), fprintf(), etc.)
...	data for format string

Returns: number of bytes in *@a buf, excluding 0-termination

{
  int ret;
  va_list args;
 
  va_start (args, format);
  ret = vsnprintf (NULL, 0, format, args);
  va_end (args);
  GNUNET_assert (ret >= 0);
  *buf = GNUNET_malloc (ret + 1);
  va_start (args, format);
  ret = vsprintf (*buf, format, args);
  va_end (args);
  return ret;
}

◆ GNUNET_snprintf()

int GNUNET_snprintf	(	char *	buf,
		size_t	size,
		const char *	format,
			...
	)

Like snprintf(), just aborts if the buffer is of insufficient size.
