Using the WebQoS API

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.

process to be in. Refer to “class Values” for a list of
