Re: Where is syscall.msync()?

[Kevin Gillette]

In case it got overlooked, you can, in the meantime, call syscall.Syscall(syscall.SYS_MSYNC, ...)

How do you call msync() for an mmap()-ed []byte then? 

[Rio]

This is what I got after learning about syscall.Syscall

func msync(b []byte, flag int) (err error) {

    var _p0 unsafe.Pointer

    if len(b) > 0 {

        _p0 = unsafe.Pointer(&b[0])

    } else {

        _p0 = unsafe.Pointer(&_zero)

    }

    _, _, e1 := syscall.Syscall(syscall.SYS_MSYNC,

        uintptr(_p0), uintptr(len(b)), uintptr(flag))

    if e1 != 0 {

        err = e1

    }

    return

}

Basically I followed the pattern in syscall.Madvise. I've no idea if I did it correctly. Any thought on this?

Perhaps this might be helpful.
