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/vsnprintf.c | 5 ----- 1 file changed, 5 deletions(-) (limited to 'src/stdio/vsnprintf.c') diff --git a/src/stdio/vsnprintf.c b/src/stdio/vsnprintf.c index b3510a63..409b9c85 100644 --- a/src/stdio/vsnprintf.c +++ b/src/stdio/vsnprintf.c @@ -45,11 +45,6 @@ int vsnprintf(char *restrict s, size_t n, const char *restrict fmt, va_list ap) .cookie = &c, }; - if (n > INT_MAX) { - errno = EOVERFLOW; - return -1; - } - *c.s = 0; return vfprintf(&f, fmt, ap); } -- cgit v1.2.1
