Hi, What will happen when getchar () (or some other operation) is called from userspace. I would like to know all the trace until you receive the character from kernel to userspace. My rough understanding is: getchar calls library function which calls system call...etc. I need some proper explanation. Can any one clarify me on this. Thanks. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
