# hv_gic_set_spi(_:_:)

Triggers a shared peripheral interrupt (SPI).

## Declaration

```swift
func hv_gic_set_spi(_ intid: UInt32, _ level: Bool) -> hv_return_t
```

## Parameters

- `intid`: The interrupt number of the SPI.
- `level`: The high- or low-level state for the interrupt. Setting the level also causes an edge on the line for an edge triggered interrupt.

## Return Value

Return Value HV_SUCCESS on success; otherwise, an error code.

## Discussion

Discussion Setting a level value causes level interrupts. To cause an edge interrupt, call this method with a level of true. The framework ignores a level of false for an edge interrupt. An interrupt identifier outside of hv_gic_get_spi_interrupt_range(_:_:) or in the message signaled interrupt (MSI) range returns a HV_BAD_ARGUMENT error code.
