hpe5250a_closeList_Q
This function will query the instrument for the channels closed given in the
’closechan_list’.
The parameter ’closechan_list’ is an array of integers with each integer representing
one channel. The last number of the ’closechan_list’ should be "0" (numeric zero)
to identify the end of the list. The maximum number of channels that can be
specified by the list is 100.
The ’close_status’ parameter is an array of integers containing the return values of
the query. The ’close_status’ array returned will correspond one to one with
’closechan_list’ parameter.
