unsigned long PIPLX_MaskBit (long session, unsigned long cardNumber, unsigned long outputSubunit, unsigned long bitNumber, int action);
Mask or unmask a single output bit.
Masking disables the corresponding switch for the PIPLX_OpBit, PIPLX_OpCrosspoint and PIPLX_WriteSub functions. This facility is particularly useful for matrix sub-units, where it can be used to guard against programming errors that could otherwise result in damage to matrix switches or external circuits. Note that PIPLX_MaskCrosspoint allows more straightforward use of row/column co-ordinates with matrices.
