PTHREAD_SCHEDPARAM(3)	 BSD Library Functions Manual	 PTHREAD_SCHEDPARAM(3)

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

LIBRARY
     POSIX Threads Library (libpthread,	-lpthread)

SYNOPSIS
     #include <pthread.h>

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

     int
     pthread_getschedparam(pthread_t thread, int *restrict policy,
	 struct	sched_param *restrict 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), SCHED_RR
     (round-robin), or SCHED_OTHER (timesharing).  Valid thread	priorities
     (accessed via param-_sched_priority) must be within the range returned by
     the sched_get_priority_min(2) and sched_get_priority_max(2) system	calls.

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

ERRORS
     The pthread_setschedparam() function will fail if:

     [EINVAL]		Invalid	value for policy.

     [ENOTSUP]		Invalid	value for scheduling parameters.

     [ESRCH]		Non-existent thread thread.

     The pthread_getschedparam() function will fail if:

     [ESRCH]		Non-existent thread thread.

SEE ALSO
     sched_get_priority_max(2),	sched_get_priority_min(2)

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