pthread_attr_setschedpolicy, pthread_attr_getschedpolicy - set/get scheduling policy attribute in thread attributes object
#include <pthread.h> 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
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
In order for the policy setting made by pthread_attr_setschedpolicy() to have effect when calling pthread_create(3), the caller must use pthread_attr_setinheritsched(3) to set the inherit-scheduler attribute of the attributes object
attr to PTHREAD_EXPLICIT_SCHED.
On success, these functions return 0; on error, they return a nonzero error number.
