+
+Creates an C<IO::File> opened for read/write on a newly created temporary
+file. On systems where this is possible, the temporary file is anonymous
+(i.e. it is unlinked after creation, but held open). If the temporary

C<open> accepts one, two or three parameters. With one parameter,
-it is just a front end for the built-in C<open> function. With two
+it is just a front end for the built-in C<open> function. With two or three
parameters, the first parameter is a filename that may include
whitespace or other special characters, and the second parameter is
the open mode, optionally followed by a file permission value.
If C<IO::File::open> receives a Perl mode string ("E<gt>", "+E<lt>", etc.)
-or a POSIX fopen() mode string ("w", "r+", etc.), it uses the basic
-Perl C<open> operator.
+or an ANSI C fopen() mode string ("w", "r+", etc.), it uses the basic
+Perl C<open> operator (but protects any special characters).
If C<IO::File::open> is given a numeric mode, it passes that mode
and the optional permissions value to the Perl C<sysopen> operator.
-For convenience, C<IO::File::import> tries to import the O_XXX
-constants from the Fcntl module. If dynamic loading is not available,
-this may fail, but the rest of IO::File will still work.
+The permissions default to 0666.
+
+For convenience, C<IO::File> exports the O_XXX constants from the
+Fcntl module, if this module is available.
