# in order to do this, we are also generating a python representation (using
# ctypesgen) of ../../../../../include/uapi/linux/comedi.h.
# This allows us to sort NI signal/terminal names numerically to use a binary
# search through the device_routes tables to find valid routes.

# Note:  One could also use ctypeslib in order to generate these files.  The
# caveat is that ctypeslib does not do a great job at handling macro functions.
# The make rules are as follows:
# comedi.h.xml : $(INC_UAPI)/linux/comedi.h
# 	# note that we have to use PWD here to avoid h2xml finding a system
# 	# installed version of the comedilib/comedi.h file
