You should have been able to find these functions by using "grep" or
other similar tools (hint: look under tools/libxc).

Had you done so you would have found that they use the xtl logger
infrastructure. xch->error_handler is the logger passed to
xc_interface_open(), the behaviour of which is documented in the header.
