From a9d99b32a34589777e95898dac0597dbfbede4ea Mon Sep 17 00:00:00 2001 From: Dan Streetman Date: Tue, 3 Jan 2017 14:31:45 -0500 Subject: libudev-util: change util_replace_whitespace to return number of chars in dest Instead of returning 0, which is unhelpful, return the number of chars copied into the dest string. This allows callers that care about that to easily use it, instead of having to calculate the strlen. No current users of the function check the return value, so this does not break any existing code; it is used in the following patch. --- src/libudev/libudev-util.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/libudev/libudev-util.c') diff --git a/src/libudev/libudev-util.c b/src/libudev/libudev-util.c index 574cfeac85..a9819b9db3 100644 --- a/src/libudev/libudev-util.c +++ b/src/libudev/libudev-util.c @@ -186,7 +186,7 @@ int util_replace_whitespace(const char *str, char *to, size_t len) to[j++] = str[i++]; } to[j] = '\0'; - return 0; + return j; } /* allow chars in whitelist, plain ascii, hex-escaping and valid utf8 */ -- cgit v1.2.3-54-g00ecf
