Dear Sir,

Is there is any way, one can know the type of record, if I know the PV name.

e.g. I have a analog input record Py:ai1

 >>> pv=epics.PV('Py:ai1')
 >>> pv.type
'double'
 >>> pv.count
1
 >>> pv.get_ctrlvars()

{'status': 17, 'lower_disp_limit': 0.0, 'upper_disp_limit': 0.0,

'severity': 3, 'upper_ctrl_limit': 0.0, 'lower_alarm_limit': nan,

'precision': 0, 'upper_alarm_limit': nan, 'lower_warning_limit': nan,

'upper_warning_limit': nan, 'units': '', 'lower_ctrl_limit': 0.0}

 >>> pv.info <http://pv.info>

"== Py:ai1 (native_double) ==\n value = 1\n char_value = '1'\n

 count = 1\n type = double\n units = \n precision

 = 0\n host = trunk.codac.iter.org:42293

<http://trunk.codac.iter.org:42293>\n access = read/write\n

status = 17\n severity = 3\n timestamp = 1303134187.996

(2011-04-18 15:43:07.996138)\n upper_ctrl_limit = 0.0\n

lower_ctrl_limit = 0.0\n upper_disp_limit = 0.0\n

lower_disp_limit = 0.0\n upper_alarm_limit = nan\n

lower_alarm_limit = nan\n upper_warning_limit = nan\n

lower_warning_limit = nan\n PV is internally monitored, with 0

user-defined callbacks:\n============================="

How does I get it is of record type analog input e.g. (ai). One way is

to get it from output string . Is there is a simple way ?
