HP WebQoS Software manual Wqsetproccls

Using the WebQoS API

wq_set_proc_cls()

wq_set_proc_cls()

Sets the process group of the current process. For a multithreaded process, all threads are set to the same specified process group.

A process is only allowed to change its process group to the value(s) specified in the file /etc/opt/webqos/svccls.allow. By default, a process cannot change its process group. Refer to the svccls.allow file for an explanation of how to configure this file. A copy of this file can be found in Appendix A , “Sample Programs, Configuration, and Header Files,” on page 33.
