Subject Re: [users@httpd] How to use shared memory btw mpm workers in custom module
Date Wed, 03 Dec 2014 23:01:39 GMT
i'm using 2.2.x i've implemented a shared memory segment using apr_shm_*
functions but i've noticed that if i access to this segment
in ap_hook_handler i can see it and operate with it, but
in ap_hook_translate_name the pointer to the shm segment is null.

Any idea or suggestion?

Thanks
