From 809ff8cf90254921ea38eb6fa1ce326d9008513b Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 4 Jan 2017 19:48:21 -0500 Subject: treat base 1 as an error in strtol-family functions ISO C and POSIX only specify behavior for base arguments of 0 and 2-36; POSIX mandates an EINVAL error for unsupported bases. it's not clear that there's a requirement for implementations not to "support" additional bases as an extension, but "base 1" did not work in any meaningful way anyway, so it should be considered unsupported and thus an error. --- src/internal/intscan.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/internal/intscan.c b/src/internal/intscan.c index 65d497ec..a4a5ae86 100644 --- a/src/internal/intscan.c +++ b/src/internal/intscan.c @@ -29,7 +29,7 @@ unsigned long long __intscan(FILE *f, unsigned base, int pok, unsigned long long int c, neg=0; unsigned x; unsigned long long y; - if (base > 36) { + if (base > 36 || base == 1) { errno = EINVAL; return 0; } -- cgit v1.2.1
