A few examples are the http and ftp tdeioslaves, +which using nearly identical methods will retrieve data from an http or +ftp server respectively. + +Well, that's nice. How do they work? + +To understand it, you'll need two ice cubes, a pair of handcuffs, and a +ferret. Some Crisco (or other shortening) is optional. Well, that aside, +this document focuses on the business end of the whole tdeio library. The +ioslave. See the documentation of the SlaveBase class for the methods +you need to reimplement, and see +http://developer.kde.org/documentation/design/kde/ioslaves/ for more docu +online. + +That's nice, but how can I use it? + +Any time you'd like to use non blocking IO over a high level protocol +(such as HTTP or FTP) a tdeioslave is for you. + +That's nice, but how do I use it? + +Basically, you create "jobs" by calling a public TDEIO::blah method +(the correct prototypes, etc, are in tdeio/job.h). Once this is done, you +connect to the result() signal, and wait for the result. There are +other signals emitted by jobs, see tdeio/jobclasses.h. Once again, +see the online documentation for more. + + +If you are interested in working on an ioslave, +the following slaves are severely lacking in functionality: + + SMTP + SMB + +------------- + +Original document by Rich. +Updated for KDE 2 by David. + |
