Disables the switch block with respect to the MVIP bus.

DWORD swiDisableSwitch ( SWIHD swihd)

swihd Handle returned by swiOpenSwitch.

• SUCCESS
• CTAERR_DRIVER_ERROR
  The underlying driver retrieved an unrecognized error. Call swiGetLastError to retrieve the MVIP device error code.
• CTAERR_INVALID_HANDLE
  swihd is not a valid switch handle.

• None.

This function can be used to put the output buffers to the MVIP bus into the high impedance state. This function does not change the state of the switch block outputs. Further switching commands can be made on the swihd. However, they will not take effect until swiEnableSwitch is called.

The effect of swiDisableSwitch on the local (or external network side) of the MVIP switch block is dependent on the MVIP device implementation.

If CTAERR_DRIVER_ERROR is returned, call swiGetLastError to retrieve the MVIP device error code.
