From: Gerd Moellmann Date: Thu, 15 Mar 2001 09:44:10 +0000 (+0000) Subject: (store_symval_forwarding): Add parameter BUF. If BUF is X-Git-Tag: emacs-pretest-21.0.101~306 X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=7a283f3621d1901aa66313973d67a868bc8f4404;p=emacs.git (store_symval_forwarding): Add parameter BUF. If BUF is non-null, set a per-buffer value in BUF instead of the current buffer. (swap_in_global_binding, swap_in_symval_forwarding, Fset_default): Call store_symval_forwarding with BUF null. (set_internal): Call store_symval_forwarding with the BUF parameter passed to set_internal. Formerly, the value was always set in the current buffer; the buffer recorded in specbind for this case wasn't used. (arith_driver): Reindent. --- diff --git a/src/data.c b/src/data.c index a85c3c0179a..b635cb5619b 100644 --- a/src/data.c +++ b/src/data.c @@ -1,5 +1,6 @@ /* Primitive operations on Lisp data types for GNU Emacs Lisp interpreter. - Copyright (C) 1985,86,88,93,94,95,97,98,99,2000 Free Software Foundation, Inc. + Copyright (C) 1985,86,88,93,94,95,97,98,99, 2000, 2001 + Free Software Foundation, Inc.
