NAME
rtsched - execute process with real-time priority

SYNOPSIS
rtsched -s scheduler -p priority command [arguments]

rtsched [ -s scheduler ] -p priority -P pid

DESCRIPTION
Rtsched executes command with POSIX or HP-UX real-time priority, or
changes the real-time priority of currently executing process pid.
----------------------------------------------------------------------------

this is what I found when I checked the man page of the rtsched. This basically tells about the process scheduling on HP-UX.
And my program illustrated above only playing with the standard pthreads.
Can you put more focus on this.
I did not get what you wanted to suggest.
Please respond and correct me if I am wrong here.

NAME
pthread_attr_getschedparam, pthread_attr_setschedparam -- thread attribute operations SYNOPSIS
#include <pthread.h> int pthread_attr_getschedparam(const pthread_attr_t *restrict attr, struct sched_param *restrict param); int pthread_attr_setschedparam(pthread_attr_t *restrict attr, const struct sched_param *restrict param); DESCRIPTION
Thread attributes are used to specify parameters to pthread_create(). One attribute object can be used in multiple calls to pthread_create(), with or without modifications between calls. pthread_attr_getschedparam() and pthread_attr_setschedparam() get and set the scheduling parameters within the attr argument. See /usr/include/sched.h for the definition of struct sched_param. The sched_priority field of struct sched_param can be set to SCHED_OTHER, SCHED_FIFO and SCHED_RR. RETURN VALUES
If successful, these functions return 0. Otherwise, an error number is returned to indicate the error. pthread_attr_getschedparam(), on success, will copy the value of the thread's scheduling parameter attribute to the location pointed to by the second function parameter. ERRORS
pthread_attr_getschedparam() will fail if: [EINVAL] Invalid value for attr. pthread_attr_setschedparam() will fail if: [EINVAL] Invalid value for attr. [ENOTSUP] Invalid value for param. SEE ALSO
pthread_create(3), pthread_attr_init(3), pthread_attr_setinheritsched(3) STANDARDS
pthread_attr_setschedparam(), pthread_attr_getschedparam() conform to Version 2 of the Single UNIX Specification (``SUSv2'') BSD
