Hello All,

Can I call userspace function from kernel module ? Actually I need to process some data in user space for every event occured in kernel module.

user space function or user space program? for later, IIRC you can use usermode_helper... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
