Darren Tucker <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from Darren Tucker <[email protected]> --- Sigh. From the OpenBSD closefrom(2) man page: """ int closefrom(int fd); [...] HISTORY The closefrom() function first appeared in Solaris 9 and has been available since OpenBSD 3.5. """ However in glibc 2.34: $ grep closefrom posix/unistd.h extern void closefrom (int __lowfd) __THROW; (Despite its presence under posix/, POSIX does not specify closefrom(): https://pubs.opengroup.org/onlinepubs/9699919799/functions/close.html """ The standard developers rejected a proposal to add closefrom() to the standard. Because the standard permits implementations to use inherited file descriptors as a means of providing a conforming environment for the child process, it is not possible to standardize an interface that closes arbitrary file descriptors above a certain value while still guaranteeing a conforming environment. """ Of the systems that I have at hand: - on OpenBSD 6.9, NetBSD 8 and DragonFlyBSD 6, MINIX3 closefrom returns int. - on Solaris 10, FreeBSD 12 closefrom return void. so it's already a tire fire. I vaguely recall a reason it doesn't include openbsd-compat.h. We might be able to get away with just config.h and HAVE_CLOSEFROM. -- You are receiving this mail because: You are watching someone on the CC list of the bug.
