PTHREAD_ATTR(3) 					   BSD Library Functions Manual 					   PTHREAD_ATTR(3)

NAME

     pthread_attr_getschedpolicy, pthread_attr_setschedpolicy -- thread attribute operations

SYNOPSIS

     #include <pthread.h>

     int
     pthread_attr_getschedpolicy(const pthread_attr_t *restrict attr, int *restrict policy);

     int
     pthread_attr_setschedpolicy(pthread_attr_t *attr, int policy);

DESCRIPTION

     Thread attributes are used to specify parameters to pthread_create().  One attribute object can be used in multiple calls to
     pthread_create(), with or without modifications between calls.

     The functions pthread_attr_setschedpolicy() and pthread_attr_getschedpolicy(), set and get the attribute in the attr argument related to the
     scheduling policy.  The value for the aforementioned attribute can be SCHED_FIFO, SCHED_RR and SCHED_OTHER.

RETURN VALUES

     If successful, these functions return 0.  Otherwise, an error number is returned to indicate the error.  pthread_attr_getschedpolicy(), on
     success, will copy the value of the thread's scheduling policy attribute to the location pointed to by the second function parameter.

ERRORS

     pthread_attr_getschedpolicy() will fail if:

     [EINVAL]		Invalid value for attr.

     pthread_attr_setschedpolicy() will fail if:

     [EINVAL]		Invalid value for attr.

     [ENOTSUP]		Invalid or unsupported value for policy.

STANDARDS

     pthread_attr_setschedpolicy(), pthread_attr_getschedpolicy() conform to Version 2 of the Single UNIX Specification (``SUSv2'')
