Parameters

  device | The device to connect to.
  service | The service descriptor returned by lockdownd_start_service.

  data | Buffer that will be filled with the data received
  size | Number of bytes to receive
  received | Number of bytes received (can be NULL to ignore)
  timeout | Maximum time in milliseconds to wait for data.

Returns
  DEBUGSERVER_E_SUCCESS on success, DEBUGSERVER_E_INVALID_ARG when one or more parameters are invalid, DEBUGSERVER_E_MUX_ERROR when a communication error occurs, or DEBUGSERVER_E_UNKNOWN_ERROR when an unspecified error occurs.

## ◆ debugserver_client_send()

| ) |  |

Sends raw data using the given debugserver service client.

Parameters

  client | The debugserver client to use for sending
  data | Data to send
  size | Size of the data to send
  sent | Number of bytes sent (can be NULL to ignore)

Returns
  DEBUGSERVER_E_SUCCESS on success, DEBUGSERVER_E_INVALID_ARG when one or more parameters are invalid, or DEBUGSERVER_E_UNKNOWN_ERROR when an unspecified error occurs.

## ◆ debugserver_client_send_command()
