# PortAudio Repository .def file checker

#
|
|
# Run this script from the root of the repository using the command:
|
|
# python pa_compare_def_files.py
|
|
#
|
|
# The PortAudio repository contains two (semi-redundant) .def
|
|
# files that specify exported symbols for Windows dynamic link libraries.
|
|
#
|
|
# This script checks that the two .def files export the same symbols
|
|
# using the same ordinals.
|
|
#
|
|
# The .def files are:
|
|
#
|
|
# 1. msvc/portaudio.def
|
|
# 2. cmake/portaudio.def.in
|
|
#
|
|
# The CMake .def.in file is an input that generates a .def file
|
|
# with host-api-specific symbols commented out when a particular host API
|
|
# is not built.
