pthread_attr_setschedpolicy, pthread_attr_getschedpolicy - set/get scheduling policy attribute in thread attributes object
int pthread_attr_setschedpolicy(pthread_attr_t *attr ", int " policy ); int pthread_attr_getschedpolicy(const pthread_attr_t *attr ", int " *policy );
Compile and link with -pthread.
The pthread_attr_setschedpolicy() function sets the scheduling policy attribute of the thread attributes object referred to by attr 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(7).
The pthread_attr_getschedpolicy() returns the scheduling policy attribute of the thread attributes object attr in the buffer pointed to by policy.
On success, these functions return 0; on error, they return a nonzero error number.
pthread_attr_setschedpolicy() can fail with the following error:
POSIX.1 also documents an optional ENOTSUP error ("attempt was made to set the attribute to an unsupported value") for pthread_attr_setschedpolicy().
|EINVAL||Invalid value in policy.|
