(file descriptor in r0)
sys fstat; buf fstat(fildes, buf)
struct inode *buf; This call is identical to except that
it operates on open files instead of files given by name. It
is most often used to get the status of the standard input

error bit (c-bit) is set if the file descriptor is unknown;
from C, a 1 return indicates an error, 0 indicates
success.
