From 55b405c779348dc0216f82d153d0e36933db563c Mon Sep 17 00:00:00 2001 From: "Richard M. Stallman" Date: Mon, 8 Sep 1997 10:09:15 +0000 Subject: (ENCODE_FILE): New macro. (Ffile_attributes): Encode the file names to operate on. (file_name_completion): Do completion on encoded name, then decode. (Fdirectory_files): Encode the argument. Decode all result file names using Vfile_name_coding_system. --- src/dired.c | 84 ++++++++++++++++++++++++++++++++++++++++++++++++------------- 1 file changed, 67 insertions(+), 17 deletions(-) (limited to 'src') diff --git a/src/dired.c b/src/dired.c index 7fc39dcd722..60fba4f6839 100644 --- a/src/dired.c +++ b/src/dired.c @@ -86,6 +86,14 @@ extern struct re_pattern_buffer *compile_pattern (); #define min(a, b) ((a) < (b) ?
