swiGetOutputState
Description
- Retrieves the state of the specified switch block outputs.
Prototype
- DWORD swiGetOutputState ( SWIHD swihd,
SWI_TERMINUS output[],
unsigned mode[],
BYTE pattern[],
SWI_TERMINUS input[],
unsigned count)
- swihd Handle returned by swiOpenSwitch.
- output Array of terminus structures for which to retrieve the state. The terminus structure is:
typedef struct
{
DWORD bus;
DWORD stream;
DWORD timeslot;
} SWI_TERMINUS;
- See swiMakeConnection for a description of these fields.
- mode Array that receives the state of the switch block outputs.
- Possible mode values are:
MVIP95_DISABLE_MODE
MVIP95_PATTERN_MODE
MVIP95_CONNECT_MODE
MVIP95_FRAMED_CONNECT_MODE
- pattern Array that receives the datum values asserted at the switch block outputs if the corresponding mode is MVIP95_PATTERN_MODE.
- input Array that receives the switch block inputs connected to the switch block outputs if mode is MVIP95_CONNECT_MODE or MVIP95_FRAMED_CONNECT_MODE.
- count Number of elements in the output, mode, pattern, and input arrays.
Return Values
Events
Details
- This function retrieves the state of specified switch block outputs.
- If the mode of the output is MVIP95_DISABLE_MODE, the switch block outputs on the MVIP bus are in their high impedance state. If a switch block output is on a local bus, the timeslots on the local bus are put into a known state. (The driver vendor must publish these states in customer documentation.)
- A mode of MVIP95_PATTERN_MODE implies that a fixed pattern is being asserted on the switch block output.
- A mode of MVIP95_CONNECT_MODE or MVIP95_FRAMED_CONNECT_MODE implies that there is a connection from the input terminus to the output terminus.
- In MVIP-90 mode, the bus field is ignored and the stream and timeslot fields are interpreted as MVIP-90 streams and timeslots.
- If CTAERR_DRIVER_ERROR is returned, call swiGetLastError to retrieve the MVIP device error code.
