-.SH NAME
-pthread_attr_setinheritsched, pthread_attr_getinheritsched \- set/get
-inherit-scheduler attribute in thread attributes object
-.SH LIBRARY
-POSIX threads library
-.RI ( libpthread ", " \-lpthread )
-.SH SYNOPSIS
-.nf
-.B #include <pthread.h>
-.P
-.BI "int pthread_attr_setinheritsched(pthread_attr_t *" attr ,
-.BI " int " inheritsched );
-.BI "int pthread_attr_getinheritsched(const pthread_attr_t *restrict " attr ,
-.BI " int *restrict " inheritsched );
-.fi
-.SH DESCRIPTION
-The
-.BR pthread_attr_setinheritsched ()
-function sets the inherit-scheduler attribute of the
-thread attributes object referred to by
-.I attr
-to the value specified in
-.IR inheritsched .
-The inherit-scheduler attribute determines whether a thread created using
-the thread attributes object
-.I attr
-will inherit its scheduling attributes from the calling thread
-or whether it will take them from
-.IR attr .
-.P
-The following scheduling attributes are affected by the
-inherit-scheduler attribute:
-scheduling policy
-.RB ( pthread_attr_setschedpolicy (3)),
-scheduling priority
-.RB ( pthread_attr_setschedparam (3)),
-and contention scope
-.RB ( pthread_attr_setscope (3)).
-.P
-The following values may be specified in
-.IR inheritsched :
-.TP
-.B PTHREAD_INHERIT_SCHED
-Threads that are created using
-.I attr
-inherit scheduling attributes from the creating thread;
-the scheduling attributes in
-.I attr
-are ignored.
-.TP
-.B PTHREAD_EXPLICIT_SCHED
-Threads that are created using
-.I attr
-take their scheduling attributes from the values specified
-by the attributes object.
-.\" FIXME Document the defaults for scheduler settings
-.P
-The default setting of the inherit-scheduler attribute in
-a newly initialized thread attributes object is
-.BR PTHREAD_INHERIT_SCHED .
-.P
-The
-.BR pthread_attr_getinheritsched ()
-returns the inherit-scheduler attribute of the thread attributes object
-.I attr
-in the buffer pointed to by
-.IR inheritsched .
-.SH RETURN VALUE
-On success, these functions return 0;
-on error, they return a nonzero error number.
-.SH ERRORS
-.BR pthread_attr_setinheritsched ()
-can fail with the following error:
-.TP
-.B EINVAL
-Invalid value in
-.IR inheritsched .
-.P
-POSIX.1 also documents an optional
-.B ENOTSUP
-error ("attempt was made to set the attribute to an unsupported value") for
-.BR pthread_attr_setinheritsched ().

-.SH HISTORY
-glibc 2.0.
-POSIX.1-2001.
-.SH BUGS
-As at glibc 2.8, if a thread attributes object is initialized using
-.BR pthread_attr_init (3),
-then the scheduling policy of the attributes object is set to
-.B SCHED_OTHER
-and the scheduling priority is set to 0.
-However, if the inherit-scheduler attribute is then set to
-.BR PTHREAD_EXPLICIT_SCHED ,
-then a thread created using the attribute object
-wrongly inherits its scheduling attributes from the creating thread.
-This bug does not occur if either the scheduling policy or
-scheduling priority attribute is explicitly set
-in the thread attributes object before calling
-.BR pthread_create (3).
-.\" FIXME . Track status of the following bug:
