From bbf39a08912df2f1f176ebea4c790ffd22ba9e65 Mon Sep 17 00:00:00 2001 From: Thomas Schwinge Date: Sun, 26 Nov 2006 23:46:46 +0000 Subject: 2006-11-27 Ben Asselstine Thomas Schwinge [task #5994 --- ``rpctrace: Consider PREFIX/shared/msgids/*.msgids by default''] * rpctrace.c: Include and . (scan_msgids_dir): New function, factored out of the code, with the change of not directly parsing the files, but instead adding them to an argz vector. (STD_MSGIDS_DIR): New definition. (options): Add new `--nostdinc' option. (main): Handle that new option. Utilize an argz vector. Include the files in STD_MSGIDS_DIR unless prohibited by the new option. --- utils/rpctrace.c | 115 +++++++++++++++++++++++++++++++++++++++---------------- 1 file changed, 83 insertions(+), 32 deletions(-) (limited to 'utils/rpctrace.c') diff --git a/utils/rpctrace.c b/utils/rpctrace.c index 6d8beb78..d80f41dd 100644 --- a/utils/rpctrace.c +++ b/utils/rpctrace.c @@ -1,6 +1,7 @@ /* Trace RPCs sent to selected ports - Copyright (C) 1998,99,2001,02,03,05,2006 Free Software Foundation, Inc. + Copyright (C) 1998, 1999, 2001, 2002, 2003, 2005, 2006 + Free Software Foundation, Inc.
