| Subject: [PATCH] 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. |
