They're not required to be. If we can detect that they are, then sure, we could use it as XDG_RUNTIME_DIR. But we need to detect as otherwise someone could set TMPDIR before starting the application. > > It could be a subdir of $TMPDIR, but then we run into a race condition > > problem of creating a secure subdir with a well-established name among > > applications.

That's why QStandardPaths has a table in the documentation listing all possibilities. For Windows, it's C:\Users\<USER> (i.e., $HOME); Blackberry is /var/tmp; Android has <APPROOT>/cache and it's not supported on iOS. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
