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. \****************************************************************************/ // // The following code instantiates the PEWriteResource function template // twice.
