Subject: src/liboping.c: Let ping_setopt() return -1 if 'value' is NULL.
X-Git-Tag: liboping-1.3.0~7^2~2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=30ee957b4843140d0d3bae39859d5624824b8feb;p=liboping.git

src/liboping.c: Let ping_setopt() return -1 if 'value' is NULL.

The manpage states that 'value' must not be NULL. Anyway, imho, it's still
better to avoid segfaults inside a library.
