HANDLE BeginUpdateResourceInternalW(LPCWSTR pwch, BOOL bDeleteExistingResources)

/*++
    Routine Description
        Begins an update of resources.  Save away the name
        and current resources in a list, using EnumResourceXxx
        api set.

    Parameters:

        lpFileName - Supplies the name of the executable file that the
        resource specified by lpType/lpName/language will be updated
        in.  This file must be able to be opened for writing (ie, not
        currently executing, etc.)  The file may be fully qualified,
        or if not, the current directory is assumed.  It must be a
        valid Windows executable file.

        bDeleteExistingResources - if TRUE, existing resources are
        deleted, and only new resources will appear in the result.
        Otherwise, all resources in the input file will be in the
        output file unless specifically deleted or replaced.

    Return Value:

    NULL - The file specified was not able to be opened for writing.
    Either it was not an executable image, the executable image is
    already loaded, or the filename did not exist.  More information may
    be available via GetLastError api.

    HANDLE - A handle to be passed to the UpdateResource and
    EndUpdateResources function.

/*++
    Routine Description
        This routine adds, deletes or modifies the input resource
        in the list initialized by BeginUpdateResource.  The modify
        case is simple, the add is easy, the delete is hard.
        The ASCII entry point converts inputs to UNICODE.

    Parameters:

        hUpdateFile - The handle returned by the BeginUpdateResources
        function.

        lpType - Points to a null-terminated character string that
        represents the type name of the resource to be updated or
        added.  May be an integer value passed to MAKEINTRESOURCE
        macro.  For predefined resource types, the lpType parameter
        should be one of the following values:

          RT_ACCELERATOR - Accelerator table
          RT_BITMAP - Bitmap resource
          RT_DIALOG - Dialog box
          RT_FONT - Font resource
          RT_FONTDIR - Font directory resource
          RT_MENU - Menu resource
          RT_RCDATA - User-defined resource (raw data)
          RT_VERSION - Version resource
          RT_ICON - Icon resource
          RT_CURSOR - Cursor resource



        lpName - Points to a null-terminated character string that
        represents the name of the resource to be updated or added.
        May be an integer value passed to MAKEINTRESOURCE macro.

        language - Is the word value that specifies the language of the
        resource to be updated.  A complete list of values is
        available in winnls.h.

        lpData - A pointer to the raw data to be inserted into the
        executable image's resource table and data.  If the data is
        one of the predefined types, it must be valid and properly
        aligned.  If lpData is NULL, the specified resource is to be
        deleted from the executable image.

        cb - count of bytes in the data.

    Return Value:

    TRUE - The resource specified was successfully replaced in, or added
    to, the specified executable image.

    FALSE/NULL - The resource specified was not successfully added to or
    updated in the executable image.  More information may be available
    via GetLastError api.

/***************************** Main Worker Function ***************************
* LONG PEWriteResFile
*
* This function writes the resources to the named executable file.
* It assumes that resources have no fixups (even any existing resources
* that it removes from the executable.)  It places all the resources into
* one or two sections. The resources are packed tightly into the section,
* being aligned on dword boundaries.  Each section is padded to a file
* sector size (no invalid or zero-filled pages), and each
* resource is padded to the afore-mentioned dword boundary.  This
* function uses the capabilities of the NT system to enable it to easily
* manipulate the data:  to wit, it assumes that the system can allocate
* any sized piece of data, in particular the section and resource tables.
* If it did not, it might have to deal with temporary files (the system
* may have to grow the swap file, but that's what the system is for.)
*
* Return values are:
*     TRUE  - file was written succesfully.
*     FALSE - file was not written succesfully.
*
* Effects:
*
* History:
* Thur Apr 27, 1989        by     Floyd Rogers      [floydr]
*   Created.
* 12/8/89   sanfords    Added multiple section support.
* 12/11/90  floydr      Modified for new (NT) Linear Exe format
* 1/18/92   vich        Modified for new (NT) Portable Exe format
* 5/8/92    bryant    General cleanup so resonexe can work with unicode
* 6/9/92    floydr    incorporate bryan's changes
* 6/15/92   floydr    debug section separate from debug table
* 9/25/92   floydr    account for .rsrc not being last-1
* 9/28/92   floydr    account for adding lots of resources by adding
*                     a second .rsrc section.
