You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: zsyscall_windows.go
    path of file: ./repos/sliver/vendor/github.com/tailscale/certstore
    
    the code of the file until where you have to start completion: // Code generated by 'go generate'; DO NOT EDIT.

package certstore

import (
	"syscall"
	"unsafe"

	"golang.org/x/sys/windows"
)

var _ unsafe.Pointer

// Do the interface allocations only once for common
// Errno values.
const (
	errnoERROR_IO_PENDING = 997
)

var (
	errERROR_IO_PENDING error = syscall.Er
    
func cryptGetHashParam(hHash cryptHashHandle, dwParam uint32, pbData unsafe.Pointer, pdwDataLen *uint32, dwFlags uint32) (err error) {
	r1, _, e1 := syscall.Syscall6(procCryptGetHashParam.Addr(), 5, uintptr(hHash), uintptr(dwParam), uintptr(pbData), uintptr(unsafe.Pointer(pdwDataLen)), uintptr(dwFlags), 0)
	if r1 == 0 {
		err = errnoErr(e1)
	}
	return
}
