[Klone-users] Windows service : change and know the execution path

Hello Mickael,

if KLone has been started by the Service Manager the ctx->hServiceStatus will be set:

--------------------------------------------------
#include <klone/context.h>
if(ctx->hServiceStatus)
	; /* service mode */
else
	; /* application mode */
--------------------------------------------------


Also "GetModuleFileName(GetModuleHandle(NULL), buffer, bufsz)" should return the full path of the kloned executable; I'm not 100% sure that it works properly in service mode but it's worth a try :)

bye,
stefano
