/****************************************************************************
PROGRAM: updr16.cpp
PURPOSE: Contains API Entry points and routines for updating resource
sections in exe/dll
FUNCTIONS:
EndUpdateResource(HANDLE, BOOL) - end update, write changes
UpdateResource(HANDLE, LPSTR, LPSTR, WORD, PVOID)
- update individual resource
BeginUpdateResource(LPSTR) - begin update
16 Bit version to update win32 binaries [alessanm] - 26/07/1993
Changed Rtl* fns to use combination of far & huge heap.
Added mem-use reporting fns; grep MEM_STATISTICS. [MikeCo] - 8/17/1994
Port to 32-bit and used for Win95 IME Generator, ouput as an .OBJ -
v-guanx 8/15/1995
delete HUGE & far
HPUCHAR ==> BYTE *

/***************************** 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.
* 7/27/93 alessanm ported to win16 for Chicago
