You can access your module main configuration with
ngx_http_cycle_get_module_main_conf()  through the global ngx_cycle
that has the module contexts already set up by the shm initialization
time. You can also access the configuration from the module
init_process() method that is explicitly given the cycle. Either way,
you can pass any parameters you need to the shm zone constructor
through the zone data field that is to be installed right after the
shm zone is added  at the module configuration time.
