+# NEED: we could provide a special support for this to save typing and duplication here.
+# It could be eigher:
+#	csizeof[struct audio_buf_info]
+# Note: we probalby want to use sizeof as replacement for current bytesize.
+# Note: the argument is not necessary a struct, so we need to pronounce struct as well.
+# Or more generic form would be something along the following lines:
+#	ceval[`sizeof(struct audio_buf_info)`]
+# as replacement for any one-off defines.
