NAME
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_getschedparam(), 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.
