Read lines from the log file.

Parameters

size	Specifies the maximum number of bytes to be received. The server will ensure that the returned message doesn't exceed the given size.
response	The response callback. The Ice runtime calls this function from an Ice thread pool thread. If you set Ice::InitializationData::executor, the executor determines the thread that executes this function. It accepts: returnValue true if EOF is encountered. lines The lines read from the file. If there was nothing to read from the file since the last call to read, an empty sequence is returned. The last line of the sequence is always incomplete (and therefore no newline character should be added when writing the last line to the output device).
exception	The exception callback. The Ice runtime calls this function from an Ice thread pool thread. If you set Ice::InitializationData::executor, the executor determines the thread that executes this function.
sent	The sent callback. The Ice runtime calls this function when the request is accepted by the transport. When the request is accepted synchronously, the Ice runtime calls this function from the current thread and passes true as argument. When the request is accepted asynchronously, the Ice runtime calls this function from an Ice thread pool thread and passes false as argument. If you set Ice::InitializationData::executor, the executor determines the thread that executes this function in the asynchronous case.
context	The request context.

Returns

A function that can be called to cancel the invocation locally.
