Passing xc types such as chanends through C calling stack

[tuck1s]

I think it's OK to have functions call each other such as

A function in toplevel.xc, calls a function in midlle.c, which calls a function in driver.xc

(The sc_sdcard module is an example of this).

But is it possible to pass data types such as streaming chanend's as parameters?  The C code would of course not be able to do anything with such parameters, but if they can be passed on down to .xc that would be very useful (e.g. doing streamed I/O rather than byte arrays).

I found an answer here: http://www.xcore.com/wiki/index.php/Usi ... rts_in_C/C++ that works.
