From 27373e442747010dfc195296c0705f67e905a611 Mon Sep 17 00:00:00 2001 From: Thomas Hindoe Paaboel Andersen Date: Sat, 30 Nov 2013 23:45:31 +0100 Subject: [PATCH] util.c: check if return value from ttyname_r is > 0 instead of != 0 We must return a negative error code from getttyname_malloc but that would not be the case if ttyname_r returned a negative value. ttyname_r should only return EBADF, ENOTTY, or ERANGE so it should be safe to change. --- src/shared/util.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git src/shared/util.c src/shared/util.c index 38134ae..206fc80 100644 --- src/shared/util.c +++ src/shared/util.c @@ -2501,7 +2501,7 @@ int getttyname_malloc(int fd, char **r) { assert(r); k = ttyname_r(fd, path, sizeof(path)); - if (k != 0) + if (k > 0) return -k; char_array_0(path); -- 1.7.9.2
