-.SH NAME
-pthread_attr_setschedpolicy, pthread_attr_getschedpolicy \- set/get
-scheduling policy attribute in thread attributes object
-.SH LIBRARY
-POSIX threads library
-.RI ( libpthread ", " \-lpthread )
-.SH SYNOPSIS
-.nf
-.B #include <pthread.h>
-.P
-.BI "int pthread_attr_setschedpolicy(pthread_attr_t *" attr ", int " policy );

-.SH DESCRIPTION
-The
-.BR pthread_attr_setschedpolicy ()
-function sets the scheduling policy attribute of the
-thread attributes object referred to by
-.I attr
-to the value specified in
-.IR policy .
-This attribute determines the scheduling policy of
-a thread created using the thread attributes object
-.IR attr .
-.P
-The supported values for
-.I policy
-are
-.BR SCHED_FIFO ,
-.BR SCHED_RR ,
-and
-.BR SCHED_OTHER ,
-with the semantics described in
-.BR sched (7).
-.\" FIXME . pthread_setschedparam() places no restriction on the policy,
-.\" but pthread_attr_setschedpolicy() restricts policy to RR/FIFO/OTHER
-.\" http://sourceware.org/bugzilla/show_bug.cgi?id=7013
-.P
-The
-.BR pthread_attr_getschedpolicy ()
-returns the scheduling policy attribute of the thread attributes object
-.I attr
-in the buffer pointed to by
-.IR policy .
-.P
-In order for the policy setting made by
-.BR pthread_attr_setschedpolicy ()
-to have effect when calling
-.BR pthread_create (3),
-the caller must use
-.BR pthread_attr_setinheritsched (3)
-to set the inherit-scheduler attribute of the attributes object
-.I attr
-to
-.BR PTHREAD_EXPLICIT_SCHED .
-.SH RETURN VALUE
-On success, these functions return 0;
-on error, they return a nonzero error number.
-.SH ERRORS
-.BR pthread_attr_setschedpolicy ()
-can fail with the following error:
-.TP
-.B EINVAL
-Invalid value in
-.IR policy .
-.P
-POSIX.1 also documents an optional
-.B ENOTSUP
-error ("attempt was made to set the attribute to an unsupported value") for
-.BR pthread_attr_setschedpolicy ().
