PTHREAD_SETSCHEDPAR... FreeBSD Library Functions Manual	PTHREAD_SETSCHEDPAR...

NAME
     pthread_setschedparam, pthread_getschedparam -- thread scheduling parame-
     ter manipulation

SYNOPSIS
     #include <pthread.h>

     int
     pthread_setschedparam(pthread_t thread, int policy,
	 const struct sched_param *param);

     int
     pthread_getschedparam(pthread_t thread, int *policy,
	 struct	sched_param *param);

DESCRIPTION
     The pthread_setschedparam() and pthread_getschedparam() functions set and
     get the scheduling	parameters of individual threads.  The scheduling pol-
     icy for a thread can either be SCHED_FIFO (first in, first	out) or
     SCHED_RR (round-robin).  The thread priority (accessed via
     param-_sched_priority) must be within the range returned by the
     sched_get_priority_min() and sched_get_priority_max() functions.

RETURN VALUES
     If	successful, these functions return 0.  Otherwise, an error number is
     returned to indicate the error.

ERRORS
     pthread_setschedparam() will fail if:

     [EINVAL]		Invalid	value for policy.

     [ENOTSUP]		Invalid	value for scheduling parameters.

     [ESRCH]		Non-existent thread thread.

     pthread_getschedparam() will fail if:

     [ESRCH]		Non-existent thread thread.

SEE ALSO
     sched_get_priority_max(3)

STANDARDS
     pthread_setschedparam() and pthread_getschedparam() conform to Version 2
     of	the Single UNIX	Specification ("SUSv2")
