If you need to check the size, you are doing something wrong. Seriously, that is the reason. A sysfs file should be a single value, which will never overflow the buffer. > I see most of the implementations doing strcpy in the > show vectors.

Again, a single value only, it easily fits into the buffer size. thanks, greg k-h -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
