If no one has something against I'll check in these three bellow this eve:

gchar* ep_strdup(gchar* src) {
	guint len = strlen(src);
	
	return strncpy(ep_alloc(len), src, len);
}

guint8* ep_memdup(guint8* src, size_t len) {
	return memcpy(ep_alloc(len), src, len);
}

gchar* ep_strdup_printf(const gchar* fmt, ...)
{
	va_list ap;
	guint len;
	gchar* dst;

	va_start(ap,fmt);
	len = g_printf_string_upper_bound (fmt, ap);
	
	if ( len < (EMEM_PACKET_CHUNK_SIZE>>2) ) {
		dst = ep_alloc(len);
		g_vsnprintf (dst, len, fmt, ap);
	} else {
		len = EMEM_PACKET_CHUNK_SIZE>>2 - 4;

		dst = ep_alloc(len);
		g_vsnprintf (dst, len, fmt, ap);
		memcpy(dst+len,"...",4);
	}
	
	va_end(ap);
	return dst;
}
