The len2mask4 function was introduced in commit: 70473a5f8c56d8ec2e837b9b66443dc252b24da9 which is about six years later than the commit that introduced the str2mask function: 2937c0dd20f2f3c0065b671bbfe3fafcd8862eaf
This is a clean up in preparation for a str2mask6 function which will use len2mask6. --- src/standard.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/src/standard.c b/src/standard.c index acd136c27..495bae571 100644 --- a/src/standard.c +++ b/src/standard.c @@ -1022,10 +1022,8 @@ int str2mask(const char *str, struct in_addr *mask) if (!*str || (err && *err) || (unsigned)len > 32) return 0; - if (len) - mask->s_addr = htonl(~0UL << (32 - len)); - else - mask->s_addr = 0; + + len2mask4(len, mask); } return 1; } -- 2.15.1
