For ISR_WRITE_2DACS: the channel group
number of the first DAC to write to.
Port1 unsigned long: usage depends on ISRDATA
value.
For ISR_WRITE_2DACS: the channel number
(within the group) of the first DAC to write to.
Block2 unsigned long: usage depends on ISRDATA
value.
For ISR_WRITE_2DACS: the channel group
number of the second DAC to write to.
Port2 unsigned long: usage depends on ISRDATA
value.
For ISR_WRITE_2DACS: the channel number
(within the group) of the second DAC to write
to.
Returns short: User Interrupt handle (>= 0). Use this to free the user interrupt with

6.4.15.4 Transfer Data for Non-Callback Buffered User Interrupt — TCdriveNCBufferUserInterrupt
Called to drive data through the interface that has been set up using
TCsetNCBufferUserInterrupt, TCsetNCBufferUserInterruptAIO or
TCsetNCBufferUserInterrupt2. The function will perform a blocking wait, if necessary, until
one of the interrupt data buffers used for data transfer becomes available. The
TCwaitNCBufferReady or TCwaitMultiNCBufferReady functions may be used to detect when
a blocking wait would be performed. This function may be used by a HP VEE application.
SUPPORTED IN VERSION 4.00 ONWARDS.
N.B. An incompatible version of this function was included in the unreleased Version 3.0.
