Driver Functions
hpe5250a_close
hpe5250a_close
This function terminates the software connection to the instrument and deallocates
system resources. It is generally a good programming habit to close the instrument
handle when the program is done using the instrument.
Syntax
ViStatus _VI_FUNC hpe5250a_close(ViSession vi);
Parameters
vi Instrument handle returned from hpe5250a_init( ).
hpe5250a_closeCard_Q
This function will query the card for the channels closed of the specified card.
The parameter ’closechan_list’ contains the channel numbers returned by the
instrument. This will be an array of integers terminated by ’zero’ to identify the end
of the list. Array of enough length should be passed to the function.
Syntax
ViStatus _VI_FUNC hpe5250a_closeCard_Q(ViSession vi, ViInt16 close_card,
ViInt32 _VI_FAR closechan_list[ ] );
Parameters
vi Instrument handle returned from hpe5250a_init( ).
close_card Card number. 1 (card 1), 2 (card 2), 3 (card 3), or 4 (card 4) in
the normal configuration mode, or 0 (all card in the automatic
configuration mode). For the configuration mode, see
hpe5250a_func.
closechan_list[ ] Channels closed of the specified card.
