From a0902fe51010645f779e4d02cd46f35e488b8bd2 Mon Sep 17 00:00:00 2001 From: Adam Spragg Date: Mon, 23 May 2022 15:29:11 +0100 Subject: Return non-zero exit status if "compare" finds differences This makes `metastore` more useful in scripts, just to check if it found anything, in the same way as `diff` and `grep`. Note that POSIX requires that EXIT_SUCCESS is 0, and EXIT_FAILURE is 1, so I've defined EXIT_DIFFERENCES as 2 which, while different from the values `diff` and `grep` use (1 for finding something, 2 for errors), maintains a certain amount of backwards compatibility with previous versions of metastore. --- src/metaentry.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/metaentry.h') diff --git a/src/metaentry.h b/src/metaentry.h index fd28c17..497cbc2 100644 --- a/src/metaentry.h +++ b/src/metaentry.h @@ -87,7 +87,7 @@ int mentry_compare(struct metaentry *left, msettings *st); /* Compares lists of real and stored metadata and calls pfunc for each */ -void mentries_compare(struct metahash *mhashreal, +int mentries_compare(struct metahash *mhashreal, struct metahash *mhashstored, void (*pfunc)(struct metaentry *real, struct metaentry *stored, -- cgit v1.2.1
