func CreateEmptyIfNotExists(filename string)

CreateEmptyIfNotExists creates an empty file with the given filename if it does not already exist. If the parent directory of the file does not exist, the function will create it. The function is useful for ensuring that a file is present before writing to it.

Example

package main

import (
	"github.com/microsoft/go-sqlcmd/internal/io/file"
	"os"
	"path/filepath"
)

func main() {
	filename := filepath.Join(os.TempDir(), "foo.txt")

	file.CreateEmptyIfNotExists(filename)
}

	errorHandler func(err error),
	traceHandler func(format string, a ...any))
