x/sys/unix: SYS_IOCTL not defined on Solaris

[dewi-ny-je]

As written in #11113 (comment) zsysnum_solaris_amd64.go lacks

SYS_IOCTL = 54

and I get a compilation error when calling on Solaris

unix.SYS_IOCTL

[ianlancetaylor]

In fact none of the system call numbers are currently defined on Solaris.

[bradfitz]

System calls are not considered stable ABI on Solaris, so lack of SYS_* constants seems fine.

@dewi-ny-je, what's the real problem, though? SYS_IOCTL not existing is preventing you from doing something else, presumably. What are you trying to compile or do?

[AttilaFueloep]

Most probably he refers to what is beeing discussed in Bowery/prompt#8 .

@dewi-ny-je Basicaly on Solaris you have to use unix.Ioctl{Get,Set}Termios() and unix.IoctlGetWinsize(), not unix.Syscall(). So unix.SYS_IOCTL isn't needed.

[bradfitz]

So, nothing to do here then, right?

[AttilaFueloep]

Can't speak for @dewi-ny-je , but I think it can be closed.
