VISA Flush I/O Buffer

Flushes the I/O buffer.

VISA resource name specifies the resource to be opened. This control also specifies the session and class. Refer to VISA Resource Name Control for more information.
mask designates the buffer to flush. Mask 16 and mask 64 flush the receive buffer, discarding the contents of the buffer. Mask 32 and mask 128 flush the transmit buffer, discarding the contents of the buffer. Mask 32 flushes the transmit buffer by writing all the buffered data to the device, while mask 128 doesn't perform any I/O to the device. Combine the buffer masks by bit to flush more than one buffer simultaneously. Use logical OR, also known as OR-ing or adding, to combine the values. The following table lists the valid mask values and hex codes.

error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
code is the error or warning code. The default is 0. 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 or function that produced the error or warning. The default is an empty string.
dup VISA resource name is a copy of the VISA resource name that is passed out of the VISA functions. Refer to VISA Resource Name Control for more information.
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
code is 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 or function that produced the error or warning.
