// The idea of this file is to provide a static function to execute
|
|
// when the plugin (this library) is loaded. Thus the name "hook".
|
|
|
|
// For the moment, instead of a function hook to be called by the
|
|
// libbackend.so module, we have a static PythonPolicyManager object.
|
|
// This is a risk.
|
|
#warning FIXME : this code is quite a bad idea. Replace me with \
|
|
a hookable structure, and execute a pointer to function stored \
|
|
therein. See "info libtool": "dlopened modules"
