agb220xa_openList_Q

This function will query the instrument for the channels open given in the “openchan_list”.

The parameter “openchan_list” is an array of integers with each integer representing one channel. The last number of the “openchan_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 “open_status” parameter is an array of integers containing the return values of the query. The “open_status” array returned will correspond one to one with “openchan_list” parameter.

	ViInt32_VI_FAR openchan_list[ ], ViInt32_VI_FAR open_status[ ] );
Parameters	vi	Instrument handle returned from agb220xa_init( ).
	openchan_list[ ] Channel numbers to know the open status. 5 digits integer.
		ABCDE. where A: card number, BC: input port number, DE:
