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.
