2005-01-22  Christopher Faylor  <cgf@timesys.com>

2005-01-22  Christopher Faylor  <cgf@timesys.com>

	* pinfo.cc (pinfo::init): Move everything but the MapViewOfFileEx out

	PID_STATE here.
	(pinfo::init): Remove exitcode initialization.
	(pinfo::exit): Reflect change in EXITCODE_* naming.  Set flag when
	exitcode has been established.  Reflect change in arguments to
	set_process_state.

2005-01-01  Christopher Faylor  <cgf@timesys.com>
