My question maybe too simple to you,but I really want to get your help.
In fact,I am turely a new member of RT-linux community.I 've read some paper
and sample applications,I noticed that "realtime tasks can not make system call", I
wonder besides communicate with linux tasks,what and how can be done by realtime
tasks?Especially I/O operation?for an example,if I want to get keybord input
information in RT task,what function should I use?Do I need to install a RT com driver
or something else?if I do,how?
Thanks to everyone who help me!
yours xiaowu
