From 08b4600264d34e34f62ad1a32c7e355ab9cc315d Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Fri, 25 Sep 1998 21:40:23 +0000 Subject: [PATCH] (underlying_strftime): Set the buffer to a nonzero value before calling strftime, and check to see whether strftime has set the buffer to zero. This lets us distinguish between an empty buffer and an error. I'm installing this patch by hand now; it will be superseded whenever the glibc sources are propagated back to fsf.org. --- src/strftime.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/strftime.c b/src/strftime.c index de5e6b74af9..ec6068a3b28 100644 --- a/src/strftime.c +++ b/src/strftime.c @@ -742,8 +742,9 @@ my_strftime (s, maxsize, format, tp) *u++ = modifier; *u++ = format_char; *u = '\0'; + ubuf[0] = '\1'; len = strftime (ubuf, sizeof ubuf, ufmt, tp); - if (len == 0) + if (len == 0 && ubuf[0] != '\0') return 0; cpy (len, ubuf); } -- 2.39.2
