Set the thread scheduling policy attribute
#include <pthread.h> #include <sched.h> int pthread_attr_setschedpolicy( pthread_attr_t* attr, int policy );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pthread_attr_setschedpolicy() function sets the thread scheduling policy attribute in the thread attribute object attr to policy.
The policy attribute is used only if you've set the thread inherit-scheduling attribute to PTHREAD_EXPLICIT_SCHED by calling pthread_attr_setinheritsched().
For descriptions of the scheduling policies, see “Scheduling policies” in the chapter on the Neutrino microkernel in the System Architecture guide.
