DESCRIPTION
The pthread_attr_setschedpolicy() function sets the scheduling policy attribute of the thread attributes object referred to by thread to the value specified in policy. This attribute determines the scheduling policy of a thread created using the thread attributes object attr.

The pthread_attr_getschedpolicy() returns the scheduling policy attribute of the thread attributes object attr in the buffer pointed to by policy.
RETURN VALUE
On success, these functions return 0; on error, they return a non-zero error number.
ERRORS
pthread_attr_setschedpolicy() can fail with the following error:
EINVAL | Invalid value in policy. |
