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

NAME

     pthread_attr_getschedparam, pthread_attr_setschedparam -- thread attribute operations

SYNOPSIS

     #include <pthread.h>

     int
     pthread_attr_getschedparam(const pthread_attr_t *restrict attr, struct sched_param *restrict param);

     int
     pthread_attr_setschedparam(pthread_attr_t *restrict attr, const struct sched_param *restrict param);

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.

     pthread_attr_getschedparam() and pthread_attr_setschedparam() get and set the scheduling parameters within the attr argument. See
     /usr/include/sched.h
     for the definition of struct sched_param.	The sched_priority field of struct sched_param must be within the range returned by the
     sched_get_priority_min(2) and sched_get_priority_max(2) system calls.

RETURN VALUES

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

ERRORS

     pthread_attr_getschedparam() will fail if:

     [EINVAL]		Invalid value for attr.

     pthread_attr_setschedparam() will fail if:

     [EINVAL]		Invalid value for attr.

     [ENOTSUP]		Invalid value for param.

STANDARDS

     pthread_attr_setschedparam(), pthread_attr_getschedparam() conform to Version 2 of the Single UNIX Specification (``SUSv2'')
