DESCRIPTION
The functions pthread_attr_setinheritsched() and
pthread_attr_getinheritsched(), respectively, set and get
the inheritsched attribute in the attr argument.When the attribute objects are used by pthread_create(), the
inheritsched attribute determines how the other scheduling attributes of the created thread are to be set:PTHREAD_INHERIT_SCHED Specifies that the scheduling
policy and associated attributes are to be inherited from thecreating thread, and the schedul-
ing attributes in this attr argu-
ment are to be ignored.PTHREAD_EXPLICIT_SCHED Specifies that the scheduling
policy and associated attributesare to be set to the correspond-
ing values from this attribute object.The symbols PTHREAD_INHERIT_SCHED and
PTHREAD_EXPLICIT_SCHED are defined in the header
. RETURN VALUES
If successful, the pthread_attr_setinheritsched() and
pthread_attr_getinheritsched() functions return 0. Other-
wise, an error number is returned to indicate the error.ERRORS

Standard C Library Functions pthread_attr_getinheritsched(3C)
The pthread_attr_setinheritsched() or
pthread_attr_getinheritsched() functions may fail if:
EINVAL attr or inheritsched is invalid.USAGE
After these attributes have been set, a thread can be created with the specified attributes usingpthread_create(). Using these routines does not affect the
current running thread.ATTRIBUTES
