# requestSendPTPCommand(_:outData:sendCommandDelegate:didSendCommand:contextInfo:)

Sends a Picture Transfer Protocol (PTP) command to a camera asynchronously.

## Declaration

```swift
func requestSendPTPCommand(_ command: Data, outData data: Data?, sendCommandDelegate: Any, didSendCommand selector: Selector, contextInfo: UnsafeMutableRawPointer?)
```

## Discussion

Discussion Call this method only if the capabilities property contains cameraDeviceCanAcceptPTPCommands. All PTP cameras have this capability. The sendCommandDelegate must implement a function with the signature - (void)didSendPTPCommand:(NSData*)command inData:(NSData*)data response:(NSData*)response error:(NSError*)error contextInfo:(void*)contextInfo, to be called when the request is completed.
