6.4.14.4 Buffered User Interrupt Callback — TCUserCBCallback
Function to be implemented in the user’s code. The user will need to pass a pointer to the
function (which has a user-supplied name) to TCsetBufferUserInterrupt,
TCsetBufferUserInterruptAIO or TCsetBufferUserInterrupt2. It must be declared as
‘CALLBACK’. It is called when a buffers-worth of data has been read from the card during
interrupt processing, or another buffers-worth of data is required from the user to be written to
the card during interrupt processing.
SUPPORTED IN VERSION 3.00 ONWARDS.
TCUserCBCallback (h, wParam, BufSize, pBuffer)
where h short: board handle as issued by the
registerBoardEx function.
wParam unsigned integer: value as supplied by user
to TCsetBufferUserInterrupt function.
BufSize unsigned long: number of data values which
can be read from the buffer, or which must be
written to the buffer by the user.
pBuffer pointer to unsigned long: points to start of
buffer.
Returns void.
