From 4c697d5087e5f5aaa01bada73396058eed88525d Mon Sep 17 00:00:00 2001 From: Michael Forney Date: Fri, 5 Apr 2019 20:02:26 -0700 Subject: arg: Use (void *)0 instead of NULL in error case of conditional expression Even though NULL is a null pointer constant, the comma expression with NULL at the end is not. So, we must ensure that either the type of the comma expression is `char *` or `void *`, and we don't know this for NULL. --- arg.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arg.h b/arg.h index 8f93ee1..d428660 100644 --- a/arg.h +++ b/arg.h @@ -15,4 +15,4 @@ } #define EARGF(x) \ - (done_ = 1, *++opt_ ? opt_ : argv[1] ? --argc, *++argv : ((x), abort(), NULL)) + (done_ = 1, *++opt_ ? opt_ : argv[1] ? --argc, *++argv : ((x), abort(), (void *)0)) -- cgit v1.2.3
