+
+The @code{lstat()} function obtains information about the file
+associated with @code{fildes} and writes it to the area pointed
+to by the @code{buf} argument.
+
+@subheading NOTES:
+
+If the filesystem object referred to by @code{fildes} is a
+link, then the information returned in @code{buf} refers
+to the link itself.  This is in contrast to @code{fstat()}
+which follows the link.
+
+The @code{lstat()} routine is defined by BSD 4.3 and SVR4 
+and not included in POSIX 1003.1b-1996.
