+@deffnx {C Function} scm_stat (object, exception_on_error)
Return an object containing various information about the file
determined by @var{object}. @var{object} can be a string containing
a file name or a port or integer file descriptor which is open
on a file (in which case @code{fstat} is used as the underlying
system call).
+If the optional @var{exception_on_error} argument is true, which
+is the default, an exception will be raised if the underlying
+system call returns an error, for example if the file is not
+found or is not readable. Otherwise, an error will cause
+@code{stat} to return @code{#f}.

The object returned by @code{stat} can be passed as a single
parameter to the following procedures, all of which return
integers:
