From af02f4c5179675ad4e26b17ba26694a8fcde17fa Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Wed, 21 Nov 2018 17:44:14 +0100 Subject: cutils: Fix qemu_strtosz() & friends to reject non-finite sizes qemu_strtosz() & friends reject NaNs, but happily accept infinities. They shouldn't. Fix that. The fix makes use of qemu_strtod_finite(). To avoid ugly casts, change the @end parameter of qemu_strtosz() & friends from char ** to const char **. Also, add two test cases, testing that "inf" and "NaN" are properly rejected. While at it, also fixup the function documentation.
