pthread_attr_getschedparam, pthread_attr_setschedparam - get or set
schedparam attribute
SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ]
#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
The functions pthread_attr_setschedparam() and pthread_attr_getsched‐
param(), respectively, set and get the scheduling parameter attributes
in the attr argument. The contents of the param structure are defined
in <sched.h>. The only required member of param is sched_priority.
RETURN VALUES
If successful, the pthread_attr_setschedparam() and
pthread_attr_getschedparam() functions return 0. Otherwise, an error
number is returned to indicate the error.
ERRORS
The pthread_attr_setschedparam() function may fail if:
EINVAL
attr is invalid.
The pthread_attr_getschedparam() function may fail if:
EINVAL
attr or param is invalid.
USAGE
After these attributes have been set, a thread can be created with the
specified attributes using pthread_create(). Using these routines does
not affect the current running thread.
