Manipulating priority and scheduling policies
QNX SDP8.0System ArchitectureDeveloperUser
A thread's priority can vary during its execution, either from direct manipulation by the thread itself or from the kernel adjusting the thread's priority as it receives a message from a higher-priority thread.
In addition to priority, you can also select the scheduling
algorithm that the kernel will use for the thread.
Although our libraries provide a number of different ways to get and set
the scheduling parameters, your best choices are
pthread_getschedparam(),
pthread_setschedparam(),
and
pthread_setschedprio().
For information about the other choices, see
Scheduling policies
in the Programming Overview chapter of the
QNX OS Programmer's Guide.
