Overview
Reads/writes a string from/to the user buffer. If the kernel buffer provided is not large enough to hold the string, the string is truncated. The copied string is NULL-terminated. If the string is being read by the user process, it is copied and a newline '\n' is added. It is truncated if the buffer is not large enough.
Returns 0 on success.
