Set a thread's scheduling parameters attribute
#include <pthread.h> #include <sched.h> int pthread_attr_setschedparam( pthread_attr_t * attr, const struct sched_param * param );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pthread_attr_setschedparam() function sets the thread scheduling parameters attribute in the thread attribute object attr to param.
The thread scheduling parameters are used only if you've set the thread inherit scheduling attribute to PTHREAD_EXPLICIT_SCHED by calling pthread_attr_setinheritsched(). By default, a thread inherits its parent's priority.
See the entry for sched_param.
