# generate files for the windows plugin interface from a file with declarations
|
|
#
|
|
# The input for this script is generated by gcc using the following command:
|
|
#
|
|
# gcc -aux-info xyzzy $(pkg-config --cflags glib-2.0) -I ethereal-0.9.13 -c plugin_api_list.c
|
|
#
|
|
# this gives one declaration per line, with consistent spacing.
|
|
#
|
|
# with a much more elaborate parser than the one RE we have now, we could do without gcc.
