If your stream was a read stream called readStreamyour function call would be like that in Listing When you receive a or response, you find the correct object and credentials for that server and apply them. How can we improve this document? The Activity Lifecycle Chapter 4. This allows you to not have to poll your socket stream, which would slow down the thread.

Cfneteork for file-based streams, you cannot seek within a stream; once stream data has been provided or consumed, it cannot be retrieved again from the stream. Locations and Play Services Chapter First, you instantiate the stream by specifying the stream type memory, file, or socket and set any options. This message is then serialized, a process that converts the message into a raw byte stream.

In addition, the Web Kit is a set of Cocoa classes to display web content in windows.

If you set the retain and release parameters to NULLthen the system will expect you to keep the memory pointed to by the info pointer alive until the stream itself is destroyed. Using FTP read and write streams you can perform functions such as:. Start by cfnetaork a read stream.


The preferred way to use streams is with a run loop. Thus, the structure of the software layers looks like the image in Figure Similarly, the release parameter, myReleaseis a pointer to a function to release the info parameter.
