From 11fb383275d20f5f94c00425bd888a02ecbd218e Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 17 Jan 2024 18:11:58 -0500 Subject: remove INT_MAX limit on the n argument to snprintf/swprintf this was a POSIX requirement that was always in conflict with ISO C, which specified a well-defined behavior for snprintf and swprintf so long as the actual number of bytes/characters produced did not exceed INT_MAX. I originally raised this conflict for snprintf with the Austin Group as tracker issue 761, which was never resolved. it was later reported again as issue 1219, and as a result the conflicting requirement has been removed. the corresponding issue with swprintf does not seem to have been addressed, but as the same reasoning applies to it, I am removing the limitation on n for swprintf as well. --- src/stdio/vswprintf.c | 3 --- 1 file changed, 3 deletions(-) (limited to 'src/stdio/vswprintf.c') diff --git a/src/stdio/vswprintf.c b/src/stdio/vswprintf.c index fc223cf2..5e9a4dad 100644 --- a/src/stdio/vswprintf.c +++ b/src/stdio/vswprintf.c @@ -51,9 +51,6 @@ int vswprintf(wchar_t *restrict s, size_t n, const wchar_t *restrict fmt, va_lis if (!n) { return -1; - } else if (n > INT_MAX) { - errno = EOVERFLOW; - return -1; } r = vfwprintf(&f, fmt, ap); sw_write(&f, 0, 0); -- cgit v1.2.1
