Resets specified switch block outputs to their idle state.

DWORD swiDisableOutput ( SWIHD swihd,
SWI_TERMINUS output[],
unsigned count)

swihd Handle returned by swiOpenSwitch.

output Array of terminus structures containing the outputs to disable.
The terminus structure is:

typedef struct
{
DWORD bus;
DWORD stream;
DWORD timeslot;
} SWI_TERMINUS;

See swiMakeConnection for a description of these fields.

count The number of elements in the output array.

• 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.
• SWIERR_INVALID_STREAM
  One or more of the streams specified is invalid.
• SWIERR_INVALID_TIMESLOT
  One or more of the timeslots specified is invalid.

• None.

This function resets specified switch block outputs to their idle state.

If the switch block output is on the MVIP bus or on the MC1 bus, it is put into the high impedance state. If the switch block output is on the local bus, the timeslots on the local bus are put into a known state. (The driver vendor must publish these states in its customer documentation.)

In MVIP-90 mode, the bus field is ignored and the stream and timeslot fields are interpreted as MVIP-90 streams and timeslots.

Refer to Section 4.4, Disabling Output for more information.

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