Hi there,

        i have the following function in assembler (but it was for my old
compiler Borlandc v3.1 16bits).
        i really need it, and i don't know AT&T syntax.
        what thefunction actually does is move double-words from source to
dest. it is much faster than the memcpy routine from C.
        could some one translate it for AT&T format. i don't want a external
ASM file, if it is possible could you translate to a C function

        thanks for your help

; this function performs a memory copy from source to destination using 32
; bit moves
.MODEL MEDIUM,C                 ; use medium memory model C function names
.CODE                           ; begin the code segment
PUBLIC fquadcpy                 ; export function name to linker

fquadcpy PROC FAR C USES ds, dest:DWORD, source:DWORD, count:DWORD
.386
cld             ; clear the direction of movement
lds si, source  ; point ds:si at source
les di, dest    ; point es:di at destination
mov ecx,count   ; move into ecx number of words
rep movsd       ; move the data
ret
fquadcpy ENDP
END
