Set a thread's scheduling parameters attribute
#include <pthread.h>
#include <sched.h>
int pthread_attr_setschedparam(
pthread_attr_t * attr,
const struct sched_param * param );
- attr
- A pointer to the pthread_attr_t structure that defines
the attributes to use when creating new threads.
For more information, see
pthread_attr_init().
- param
- A pointer to a
sched_param
structure that defines the thread's scheduling parameters.
libc
Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The pthread_attr_setschedparam() function sets the thread scheduling parameters attribute
in the thread attribute object
attr to param.
The thread scheduling parameters are used only if you've set the
thread inherit scheduling attribute to
PTHREAD_EXPLICIT_SCHED by calling
pthread_attr_setinheritsched().
By default, a thread inherits its parent's priority.
- EOK
- Success.
- EINVAL
- Invalid thread attribute object attr.
- ENOTSUP
- Invalid thread scheduling parameters attribute param.
See the entry for
sched_param.
