    .SYNOPSIS
    Login to a VDP appliance.

    .EXAMPLE
    connect-act -acthost 10.65.5.35 -actuser admin -passwordfile pass.key
    Using a password file to login. Path to password file can be absolute or relative path.

    .EXAMPLE
    connect-act -acthost 10.65.5.35 -actuser admin -password Password123
    Example using the password on the command line itself to login.

    .EXAMPLE
    connect-act 10.65.5.35 admin -ignorecerts
    Example where certificate checking is disabled.


    .DESCRIPTION
    Connect to VDP Appliance using a username and password or by specifying -passwordfile
    which will use stored credentials.

    If no password is provided and no passwordfile flag is set, then the function will
    prompt for a password

    Using -quiet suppresses all successful messages

    SSL Certificate checking is performed during Connect-Act
    To always accept and skip the check use -ignorecerts


    .PARAMETER acthost
    Required. Hostname or IP to connect to.

    .PARAMETER actuser
    Required. Username to connect to VDP as. Same username that is used in the
    Actifio Desktop login screen.

    .PARAMETER password
    Optional. If not provided, a prompt will be presented. If provided, it can be provided
    as clear text.

    example: connect-act -acthost 10.65.5.35 -actuser admin -password Password123

    .PARAMETER passwordfile
    Optional. This is a string that instructs Connect-Act to use stored credentials as
    opposed to interactive login. In order to use -passwordfile, you must use
    save-actpassword first to save the password.

    example: connect-act -acthost 10.65.5.35 -actuser admin -passwordfile pass.key
    example: connect-act 10.65.5.35 admin -passwordfile .\pass.key
    example: connect-act 10.65.5.35 admin -passwordfile pass.key


    The password file can be a relative path or a fully qualified path to the file

    .PARAMETER quiet
    Optional. Suppresses all success messages. Use this in scripting when you
    don't want to see a successful login message. To validate the connection, check
    for variable $env:ACTSESSIONID

Function udsinfo([string]$subcommand, [switch][alias("h")]$help)
{
    <#
    .SYNOPSIS
    Executes udsinfo commands via a rest API hosted on VDP Appliance.

    .EXAMPLE
    udsinfo lsuser
    list users on connect VDP appliance.

    .EXAMPLE
    udsinfo lsapplication 12345
    List details about application id 12345

    .EXAMPLE
    udsinfo lsapplication -filtervalue appname=*db*
    List any applications that contain "db" in the name

    .EXAMPLE
    udsinfo lsapplication -filtervalue "appname=*db*&hostid=333620"
    List any applications that contain "db" in the appname and are a match
    for hostid 333620. The filtervalue here needs to be quoted because & is
    a reserved special character in Powershell.

    .EXAMPLE
    udsinfo -h
    See all the available subcommands to udsinfo

    .EXAMPLE
    udsinfo lsapplication -h
    See the help information for lsapplication subcommand.

    .DESCRIPTION
    Once you have connected to a VDP Appliance using Connect-Act, you can execute
    udsinfo with a subcommand to return information from a VDP Appliance . Udsinfo commands
    allow you to retrieve information and settings from a VDP Appliance. These commands can be
    safely executed without any danger to the system.


    use udsinfo -h to get the list of possible subcommands.

    udsinfo SUBCOMMAND -h will provide help on that specific topic.

    Help is retrieved dynamically from a VDP Appliance .

    .PARAMETER subcommand
    Required. Subcommand to udsinfo. Example: lshost, lsuser, lsapplication.

    .PARAMETER argument
    Optional. Use argument to get more information about a specific object.
    Example: lshost sql01 or lshost 2342

    .PARAMETER filtervalue
    Optional. Can be used to filter the information received from a VDP Appliance.
    Filtervalue is ignored when argument is provided.

    Example: lshost -filtervalue hostanme=exch*

    .PARAMETER help
    Optional. Use this for getting subcommand help. Needs no value.
    Example: lshost -h

    .PARAMETER args
    Arguments to be provided to the function that do not meet the requirements above.

function Set-ActAPILimit([Parameter(Mandatory = $true)]

{
    <#
    .SYNOPSIS
    Limits the number of objects returned by udsinfo commands. If you set it to 1 you will only get 1 object, such as a backup or job history.

    .EXAMPLE
    Set-ActAPILimit 1
    Sets the limit to 1

    .EXAMPLE
    Set-ActAPILimit 0
    Resets the limit to unlimited

    .DESCRIPTION
    By default udsinfo commands will continue to fetch data, 4096 objects at a time until all objects are fetched.
    This could take a long time for jobhistory. Using filters is a good choice, but if you just want example output, then you can set a limit.
    If you set it to 1 you will only get 1 object, such as a backup or job history.
    To reset to default, set the value to 0

# generate an error message
function Get-ActErrorMessage ([string]$messagetoprint)

    .SYNOPSIS
    Prints a message in a format that makes it looks like an error

    .DESCRIPTION
    When VDP returns an error you will get an errormessage and often an errorcode.
    But if the module itself generates an error we want it to look like a proper error with the same format.
    This also makes it easy to script, by looking for errormessage in returned data.
