https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D277234 Bug ID: 277234 Summary: About the definition of FILE in the freebsd-src/include/stdio.h Product: Base System Version: Unspecified Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: misc Assignee: bugs@FreeBSD.org Reporter: qianxliu@cisco.com Created attachment 248688 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D248688&action= =3Dedit The definition of FILE on the Ubuntu(Linux kernel, GNU) https://github.com/freebsd/freebsd-src/blob/09cb8031b43c8e98abb5ff9b43ff649= 031d1e808/include/stdio.h#L121 Which is similar to the Mac System. I found that Ubuntu(Linux kernel, GNU) used a different definition of FILE. I don't know what's better, but I thought Linux seemed more robust(See the png). https://github.com/freebsd/freebsd-src/blob/09cb8031b43c8e98abb5ff9b43ff649= 031d1e808/include/stdio.h#L132 which means we possibly need to force-cast the void pointers of the function parameters, and this standard seemed to be identified as a bug in the strict standard. Because the C compiler is born with the type system and void is a= lso a type. This practice may violate the principle of type inheritance. Anyway, it's the key part so I just propose my view to spark the discussion= s. --=20 You are receiving this mail because: You are the assignee for the bug.=
