DLL Ordinal Numbers

The winsock.def file for use by every Windows Sockets implementation is as follows. Ordinal values starting at 1000 are reserved for Windows Sockets implementors to use for exporting private interfaces to their DLLs. A Windows Sockets implementation must not use any ordinals 999 and below except for those APIs listed below. An application which wishes to work with any Windows Sockets DLL must use only those routines listed below; using a private export makes an application dependent on a particular Windows Sockets implementation.

LIBRARY         WINSOCK         ; Application's module name

DESCRIPTION     'BSD Socket API for Windows'

EXETYPE         WINDOWS         ; required for all windows applications

STUB            'WINSTUB.EXE'   ; generates error message if application
                                ; is run without Windows

;CODE can be FIXED in memory because of potential upcalls
CODE            PRELOAD         FIXED

;DATA must be SINGLE and at a FIXED location since this is a DLL
DATA            PRELOAD         FIXED           SINGLE

HEAPSIZE        1024
STACKSIZE       16384

; All functions that will be called by any Windows routine
; must be exported.  Any additional exports beyond those defined
; here must have ordinal numbers 1000 or above.
