C23 also supports literals with thousands separators, such as 0b0000'1111 or 0xab'cd. Are strtol* required to support this as well? /me goes and reads https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2626.pdf "It is not proposed for the strto* family of functions from the C Standard Library to support digit separators at this time" -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
