error in (no error) describes error conditions that occur before this VI runs.

	status is TRUE (X) if an error occurred before this VI ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI ran. The default is FALSE.
	code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
	code the error or warning code. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI that produced the error or warning.

backlog returns the number of samples available to read for the requested record.

instrument handle out passes a reference to your instrument session to the next VI. instrument handle is obtained from the niRFSA Initialize or the niRFSA Initialize With Options VIs and identifies a particular instrument session.
