Suppose a for-loop...
// write memory values
FOR (xor(ebx,ebx); ebx < 16 && cx <= endaddr; inc(ebx)) do
mov ([eax+ecx], dl); // fetch byte from 6502 memory
stdout.put (dl," ");
IF (ebx == 7) THEN stdout.put("-") ;ENDIF;
inc (cx);
ENDFOR;
¿How I can trap Control-C to stop the listing?
; set console handler ...
;
invoke SetConsoleCtrlHandler, main_ctrl_handler, 1
mov eax, server
somewhere else in the code
; -----------------------------------------------------------------------------
; Handler for when user presses Ctrl-C or Ctrl-Brk on the console. Stops the
; app nicely.
;
align 4
main_ctrl_handler proc event:DWORD
local error:DWORD
xor eax, eax
mov ebx, event
.if ebx == CTRL_C_EVENT \
|| ebx == CTRL_BREAK_EVENT \
|| ebx == CTRL_LOGOFF_EVENT \
|| ebx == CTRL_SHUTDOWN_EVENT \
|| ebx == CTRL_CLOSE_EVENT
; disable ctrl handler and shutdown the server
;
invoke SetConsoleCtrlHandler, main_ctrl_handler, 0
mov eax, server
invoke ExitProcess
.endif
ret
main_ctrl_handler endp
Nice code (it's in MASM but it's easy to translate to HLA syntax).
I've seen this on the HLA Standard Library Reference:
Quote
ex.ControlC ($c000013a)
If control-C checking is enabled, Windows will raise this exception whenever the user presses control-C on the console device.
The enabling of Control-C trapping is done by SetConsoleCtrlHandler only? There is no "generic" (no-platform specific) method in HLA to do this?
Thank you very much. :U
