pthread_attr_getinheritscStandard C Library Fupthread_attr_getinheritsched(3C)NAME
pthread_attr_getinheritsched, pthread_attr_setinheritsched - get or set
inheritsched attribute
SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ]
#include <pthread.h>
int pthread_attr_getinheritsched(const pthread_attr_t *restrict attr,
int *restrict inheritsched);
int pthread_attr_setinheritsched(pthread_attr_t *attr, int inher‐
itsched);
DESCRIPTION
The functions pthread_attr_setinheritsched() and pthread_attr_getinher‐
itsched(), respectively, set and get the inheritsched attribute in the
attr argument.
When the attribute objects are used by pthread_create(), the inher‐
itsched 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 the creating thread, and
the scheduling attributes in this attr
argument are to be ignored.
PTHREAD_EXPLICIT_SCHED Specifies that the scheduling policy
and associated attributes are to be set
to the corresponding values from this
attribute object.
The symbols PTHREAD_INHERIT_SCHED and PTHREAD_EXPLICIT_SCHED are
defined in the header <pthread.h>.
RETURN VALUES
If successful, the pthread_attr_setinheritsched() and pthread_attr_get‐
inheritsched() functions return 0. Otherwise, an error number is
returned to indicate the error.
ERRORS
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 using pthread_create(). Using these routines does
not affect the current running thread.
