# Conventionally there will also be:
#   libxl_test_FOO.h  interface between the "inside" and "outside" parts
# The "inside libxl" file is compiled exactly like a piece of libxl, and the
# "outside libxl" file is compiled exactly like a piece of application
# code.  They must share information via explicit libxl entrypoints.
# Unlike proper parts of libxl, it is permissible for libxl_test_FOO.c
# to use private global variables for its state.  Note that all the
# "inside" parts are compiled into a single test library, so their
# symbol names must be unique.
#
# To run these tests, either use LD_PRELOAD to get libxenlight_test.so
# loaded, or rename it to libxenlight.so so it is the target of the
# appropriate symlinks.
