Hi all
Im not really sure whether my question fits into this category or
not. Since I did't find any relevent section for pthreads under Linux
category Im sending my question to this list.
My problem is related to pthreads scheduling. I wrote a small program using
scheduling policy function. Seems the function "pthread_attr_setschedpolicy"
is not working, because Im not able see printf statement's output on
stdout(that means it is not entering the function func() at all). How ever
If I remove the statement "pthread_attr_setschedpolicy(&custom_sched_attr,
SCHED_FIFO);", I am able see the output on stdout.
Can some body throw some light about this situation. As my project is fully
depending on threads scheduling, early reply is highly appreciated.
As I am not in the mailing list please send me an e-mail at
"nraju_99@hotmail.com".
Here is the code.
#include <pthread.h>
#include <sched.h>
#include <stdio.h>
void func(void)
{
printf("Im in Function func \n");
}
main()
{
pthread_t thread;
pthread_attr_t custom_sched_attr;
struct sched_param fifo_param;
/* Initialize the attribute object */
pthread_attr_init(&custom_sched_attr);
/* Set the scheduling policy */
pthread_attr_setschedpolicy(&custom_sched_attr, SCHED_FIFO);
/* Set the scheduling priority */
fifo_param.sched_priority = 99;
pthread_attr_setschedparam(&custom_sched_attr, &fifo_param);
/* Create a thread */
pthread_create(&thread, &custom_sched_attr, (void *) func, NULL);
/* Wait for thread completion */
pthread_join(thread, NULL);
}
