Date: Sun, 20 Apr 2014 00:59:32 -0400 From: Rich Felker <dalias@...c.org> To: musl@...ts.openwall.com Subject: proposed siginfo changes I've realized that our siginfo_t structure (and also the kernel and glibc versions of it) have a bug: due to the way the union is laid out, it's illegal to initialize both si_pid and si_value. This is because __sigchld and __rt are both members of the same union and at most one member of a union can be initialized. The attached patch is a proposal for fixing this, with a more complex setup of unions and structs. I'm going to hold off on applying it immediately in case anyone has better ideas for how to do this. One possible improvement would be to set things up so we could #define away all of the __-prefixed names on GNUC or C11 compilers and thereby use anonymous structs and unions instead of the hideous preprocessor mess to access members.
