DESCRIPTION
The
pthread_attr_setschedpolicy()
function sets the scheduling policy attribute of the
thread attributes object referred to by
thread
to the value specified in
policy.
This attribute determines the scheduling policy of
a thread created using the thread attributes object
attr.
The supported values for
policy
are
SCHED_FIFO,
SCHED_RR,
and
SCHED_OTHER,
with the semantics described in
sched_setscheduler(2).
The
pthread_attr_getschedpolicy()
returns the scheduling policy attribute of the thread attributes object
attr
in the buffer pointed to by
policy.
RETURN VALUE
On success, these functions return 0;
on error, they return a non-zero error number.
ERRORS
pthread_attr_setschedpolicy()
can fail with the following error:
EINVAL
Invalid value in
policy.
POSIX.1-2001 also documents an optional
ENOTSUP
error ("attempt was made to set the attribute to an unsupported value") for
pthread_attr_setschedpolicy().
