EFAULT vs SIGSEGV on write()EFAULT vs SIGSEGV on write()Posted Jun 22, 2012 23:48 UTC (Fri) by nix (subscriber, #2304)In reply to: EFAULT vs SIGSEGV on write() by giraffedata Parent article: msync() and subtle behavioral tweaks
It's practicality. If you're trying to transparently, replace a function that normally EFAULTs on events that would cause userspace to SIGSEGV, it behooves you to behave the same way, lest you break some weird program that really depends on this. (I wrote one once. It does happen.)
