I went looking for the execveat syscall in the standard library (on 0.15.2). There are other exec-family syscalls in there, but not this one. Given the preference for file/directory handles in the standard library, this surprised me. My assumption is that there’s a reason for this other than “didn’t get to it”, so I’m curious what that reason is. It’s also entirely possible that there’s an equivalent function that I failed to find, but I did look elsewhere.

Probably because the compiler and build system have no need for it. There is a WIP project for ziglibc, so it could be that it just hasn’t been done yet.

Seems to be in master at least

If you want to just spawn child process with custom cwd, then std.process.Child supports all that just fine.

Looks like my assumption that there was a reason other than “haven’t gotten to it yet” was probably incorrect
