Resource (.RES) File Specification

The format for the .RES file is:

(/TYPE NAME FLAGS SIZE BYTES/)+

Where:

TYPE

is either a null-terminated string or an ordinal, in which instance the first byte is 0xFF followed by an INT that is the ordinal.

/* Predefined resource types */

#define RT_BITMAP              2
#define RT_MENU                3
#define RT_DIALOG              4

#define RT_AVI               103
#define RT_RESNAMES          255

NAME
is the same format as TYPE. There are no predefined names.
FLAGS
is an unsigned value containing the memory manager flags:

#define NSTYPE      0x0007   /* Segment type mask            */
#define NSCODE      0x0000   /* Code segment                 */
#define NSDATA      0x0001   /* Data segment                 */
#define NSITER      0x0008   /* Iterated segment flag        */
#define NSMOVE      0x0010   /* Moveable segment flag        */
#define NSPURE      0x0020   /* Pure segment flag            */
#define NSPRELOAD   0x0040   /* Preload segment flag         */
#define NSEXRD      0x0080   /* Execute-only (code segment), */
                              /* or read-only (data segment)  */
#define NSRELOC     0x0100   /* Segment has relocations      */
#define NSCONFORM   0x0200   /* Segment has debug info       */
#define NSDPL       0x0C00   /* 286 DPL bits                 */
#define NSDISCARD   0x1000   /* Discard bit for segment      */
#define NS32BIT     0x2000   /* 32-BIT code segment          */
#define NSHUGE      0x4000   /* Huge memory segment          */

SIZE
is a LONG value defining how many bytes follow in the resource.
BYTES
is the stream of bytes that makes up the resource.

Any number of resources can appear one after another in the .RES file.

Note: For descriptions and examples of the multimedia resource types of MIDI, RIFF, WAVE digital audio, and AVI digital video, see the OS/2 Warp Multimedia Programming Reference.
