如何检查文件名太长错误

Question

While trying to create files, I am running into os.PathError because of "file name too long". I would like to handle this scenario to do something specific. How do I go about it, apart from inspecting error.Error which returns the string "file name too long"?

Answer 1

That error is system dependent, but on unix systems the error value is syscall.ENAMETOOLONG

if pe, ok := err.(*os.PathError); ok {
    if pe.Err == syscall.ENAMETOOLONG {
        log.Fatal("name really was too long")
    }
}
