+The POSIX.1b standard introduced a few more objects which possibly can
+be implemented as object in the filesystem.  These are message queues,
+semaphores, and shared memory objects.  To allow differentiating these
+objects from other files the POSIX standard introduces three new test
+macros.  But unlike the other macros it does not take the value of the
+@code{st_mode} field as the parameter.  Instead they expect a pointer to
+the whole @code{struct stat} structure.

 @deftypefun int truncate64 (const char *@var{name}, off64_t @var{length})
 This function is similar to the @code{truncate} function.  The
 difference is that the @var{length} argument is 64 bits wide even on 32
-bits machines, which allows the handling of files with sizes up to 
+bits machines, which allows the handling of files with sizes up to
 @math{2^63} bytes.
