Yes, on Linux you can, but not with QProcess. QProcess will not give you the file descriptors for the pipes. If it did, you could simply send the pipe to another process via Unix socket file descriptor passing. Just remember to tell QProcess to closeWriteChannel(), as two processes can't read from the same pipe at the same time. (ENOTOBACCO - Empty pipe) If you really need this, you can hack QProcess and add the method. I might even accept a contribution for Qt 5.4 with the new methods. QFile and QAbstractSocket give you a file descriptor, so why not QProcess? Getting the file descriptors might be useful in other scenarios as well. For example, you may need to do some ioctls. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
