# FFEFFESCAPE

The FFEFFESCAPE structure passes hardware-specific data directly to the Force Feedback plugIn.

```
struct FFEFFESCAPE
```

## Topics

### Initializers

[`init()`](/documentation/ForceFeedback/FFEFFESCAPE/init())

[`init(dwSize:dwCommand:lpvInBuffer:cbInBuffer:lpvOutBuffer:cbOutBuffer:)`](/documentation/ForceFeedback/FFEFFESCAPE/init(dwSize:dwCommand:lpvInBuffer:cbInBuffer:lpvOutBuffer:cbOutBuffer:))

### Instance Properties

[`cbInBuffer`](/documentation/ForceFeedback/FFEFFESCAPE/cbInBuffer)

Specifies the size, in bytes, of the **lpvInBuffer** buffer.

[`cbOutBuffer`](/documentation/ForceFeedback/FFEFFESCAPE/cbOutBuffer)

On entry, specifies the size, in bytes, of the **lpvOutBuffer** buffer. On exit, specifies the number of bytes actually produced by the command.

[`dwCommand`](/documentation/ForceFeedback/FFEFFESCAPE/dwCommand)

Specifies a plugIn specific command number. Contact the hardware vendor for a list of valid commands and their parameters.

[`dwSize`](/documentation/ForceFeedback/FFEFFESCAPE/dwSize)

Size, in bytes, of this structure. This member must be initialized before the structure is used.

[`lpvInBuffer`](/documentation/ForceFeedback/FFEFFESCAPE/lpvInBuffer)

Buffer containing the data required to perform the operation.

[`lpvOutBuffer`](/documentation/ForceFeedback/FFEFFESCAPE/lpvOutBuffer)

Buffer in which the operation’s output data is returned.
