.SYNOPSIS
Creates an in-memory assembly and module

.DESCRIPTION
When defining custom enums, structs, and unmanaged functions, it is
necessary to associate to an assembly module. This helper function
creates an in-memory module that can be passed to the 'enum',
'struct', and Add-Win32Type functions.
.PARAMETER ModuleName
Specifies the desired name for the in-memory assembly and module. If
ModuleName is not provided, it will default to a GUID.
.EXAMPLE
$Module = New-InMemoryModule -ModuleName Win32

<#
.SYNOPSIS
Creates a .NET type for an unmanaged Win32 function.
Author: Matthew Graeber (@mattifestation)
License: BSD 3-Clause
Required Dependencies: None
Optional Dependencies: func
.DESCRIPTION
Add-Win32Type enables you to easily interact with unmanaged (i.e.
Win32 unmanaged) functions in PowerShell. After providing
Add-Win32Type with a function signature, a .NET type is created
using reflection (i.e. csc.exe is never called like with Add-Type).
The 'func' helper function can be used to reduce typing when defining
multiple function definitions.
.PARAMETER DllName
The name of the DLL.
.PARAMETER FunctionName
The name of the target function.
.PARAMETER EntryPoint
The DLL export function name. This argument should be specified if the
specified function name is different than the name of the exported
function.
.PARAMETER ReturnType
The return type of the function.
.PARAMETER ParameterTypes
The function parameters.
.PARAMETER NativeCallingConvention
Specifies the native calling convention of the function. Defaults to
stdcall.
.PARAMETER Charset
If you need to explicitly call an 'A' or 'W' Win32 function, you can
specify the character set.
.PARAMETER SetLastError
Indicates whether the callee calls the SetLastError Win32 API
function before returning from the attributed method.
.PARAMETER Module
The in-memory module that will host the functions. Use
New-InMemoryModule to define an in-memory module.
.PARAMETER Namespace
An optional namespace to prepend to the type. Add-Win32Type defaults
to a namespace consisting only of the name of the DLL.
.EXAMPLE
$Mod = New-InMemoryModule -ModuleName Win32
$FunctionDefinitions = @(
(func kernel32 GetProcAddress ([IntPtr]) @([IntPtr], [String]) -Charset Ansi -SetLastError),
(func kernel32 GetModuleHandle ([Intptr]) @([String]) -SetLastError),
(func ntdll RtlGetCurrentPeb ([IntPtr]) @())
)
$Types = $FunctionDefinitions | Add-Win32Type -Module $Mod -Namespace 'Win32'
$Kernel32 = $Types['kernel32']
$Ntdll = $Types['ntdll']
$Ntdll::RtlGetCurrentPeb()
$ntdllbase = $Kernel32::GetModuleHandle('ntdll')
$Kernel32::GetProcAddress($ntdllbase, 'RtlGetCurrentPeb')
.NOTES
Inspired by Lee Holmes' Invoke-WindowsApi http://poshcode.org/2189
When defining multiple function prototypes, it is ideal to provide
Add-Win32Type with an array of function signatures. That way, they
are all incorporated into the same in-memory module.

.SYNOPSIS
Creates an in-memory enumeration for use in your PowerShell session.
Author: Matthew Graeber (@mattifestation)
License: BSD 3-Clause
Required Dependencies: None
Optional Dependencies: None
.DESCRIPTION
The 'psenum' function facilitates the creation of enums entirely in
memory using as close to a "C style" as PowerShell will allow.
.PARAMETER Module
The in-memory module that will host the enum. Use
New-InMemoryModule to define an in-memory module.
.PARAMETER FullName
The fully-qualified name of the enum.
.PARAMETER Type
The type of each enum element.
.PARAMETER EnumElements
A hashtable of enum elements.
.PARAMETER Bitfield
Specifies that the enum should be treated as a bitfield.
.EXAMPLE
$Mod = New-InMemoryModule -ModuleName Win32
$ImageSubsystem = psenum $Mod PE.IMAGE_SUBSYSTEM UInt16 @{
UNKNOWN = 0
NATIVE = 1 # Image doesn't require a subsystem.
WINDOWS_GUI = 2 # Image runs in the Windows GUI subsystem.
WINDOWS_CUI = 3 # Image runs in the Windows character subsystem.
OS2_CUI = 5 # Image runs in the OS/2 character subsystem.
POSIX_CUI = 7 # Image runs in the Posix character subsystem.
NATIVE_WINDOWS = 8 # Image is a native Win9x driver.
WINDOWS_CE_GUI = 9 # Image runs in the Windows CE subsystem.
EFI_APPLICATION = 10
EFI_BOOT_SERVICE_DRIVER = 11
EFI_RUNTIME_DRIVER = 12
EFI_ROM = 13
XBOX = 14
WINDOWS_BOOT_APPLICATION = 16
}
.NOTES
PowerShell purists may disagree with the naming of this function but
again, this was developed in such a way so as to emulate a "C style"
definition as closely as possible. Sorry, I'm not going to name it

.SYNOPSIS
Creates an in-memory struct for use in your PowerShell session.
Author: Matthew Graeber (@mattifestation)
License: BSD 3-Clause
Required Dependencies: None
Optional Dependencies: field
.DESCRIPTION
The 'struct' function facilitates the creation of structs entirely in
memory using as close to a "C style" as PowerShell will allow. Struct
fields are specified using a hashtable where each field of the struct
is comprosed of the order in which it should be defined, its .NET
type, and optionally, its offset and special marshaling attributes.
One of the features of 'struct' is that after your struct is defined,
it will come with a built-in GetSize method as well as an explicit
converter so that you can easily cast an IntPtr to the struct without
relying upon calling SizeOf and/or PtrToStructure in the Marshal
class.
.PARAMETER Module
The in-memory module that will host the struct. Use
New-InMemoryModule to define an in-memory module.
.PARAMETER FullName
The fully-qualified name of the struct.
.PARAMETER StructFields
A hashtable of fields. Use the 'field' helper function to ease
defining each field.
.PARAMETER PackingSize
Specifies the memory alignment of fields.
.PARAMETER ExplicitLayout
Indicates that an explicit offset for each field will be specified.
.EXAMPLE
$Mod = New-InMemoryModule -ModuleName Win32
$ImageDosSignature = psenum $Mod PE.IMAGE_DOS_SIGNATURE UInt16 @{
DOS_SIGNATURE = 0x5A4D
OS2_SIGNATURE = 0x454E
OS2_SIGNATURE_LE = 0x454C
VXD_SIGNATURE = 0x454C
}
$ImageDosHeader = struct $Mod PE.IMAGE_DOS_HEADER @{
e_magic = field 0 $ImageDosSignature
e_cblp = field 1 UInt16
e_cp = field 2 UInt16
e_crlc = field 3 UInt16
e_cparhdr = field 4 UInt16
e_minalloc = field 5 UInt16
e_maxalloc = field 6 UInt16
e_ss = field 7 UInt16
e_sp = field 8 UInt16
e_csum = field 9 UInt16
e_ip = field 10 UInt16
e_cs = field 11 UInt16
e_lfarlc = field 12 UInt16
e_ovno = field 13 UInt16
e_res = field 14 UInt16[] -MarshalAs @('ByValArray', 4)
e_oemid = field 15 UInt16
e_oeminfo = field 16 UInt16
e_res2 = field 17 UInt16[] -MarshalAs @('ByValArray', 10)
e_lfanew = field 18 Int32
}
# Example of using an explicit layout in order to create a union.
$TestUnion = struct $Mod TestUnion @{
field1 = field 0 UInt32 0
field2 = field 1 IntPtr 0

.SYNOPSIS
Converts objects into a series of comma-separated (CSV) strings and saves the
strings in a CSV file in a thread-safe manner.
Author: Will Schroeder (@harmj0y)
License: BSD 3-Clause
Required Dependencies: None
.DESCRIPTION
This helper exports an -InputObject to a .csv in a thread-safe manner
using a mutex. This is so the various multi-threaded functions in
PowerView has a thread-safe way to export output to the same file.
Uses .NET IO.FileStream/IO.StreamWriter objects for speed.
Originally based on Dmitry Sotnikov's Export-CSV code: http://poshcode.org/1590
.PARAMETER InputObject
Specifies the objects to export as CSV strings.
.PARAMETER Path
Specifies the path to the CSV output file.
.PARAMETER Delimiter
Specifies a delimiter to separate the property values. The default is a comma (,)
.PARAMETER Append
Indicates that this cmdlet adds the CSV output to the end of the specified file.
Without this parameter, Export-PowerViewCSV replaces the file contents without warning.
.EXAMPLE
Get-DomainUser | Export-PowerViewCSV -Path "users.csv"
.EXAMPLE
Get-DomainUser | Export-PowerViewCSV -Path "users.csv" -Append -Delimiter '|'
.INPUTS
PSObject
Accepts one or more PSObjects on the pipeline.
