-.TH PTHREAD_ATTR_SETINHERITSCHED 3 2014-05-21 "Linux" "Linux Programmer's Manual"
-.SH NAME
-pthread_attr_setinheritsched, pthread_attr_getinheritsched \- set/get
-inherit-scheduler attribute in thread attributes object
-.SH SYNOPSIS
-.nf
-.B #include <pthread.h>
-
-.BI "int pthread_attr_setinheritsched(pthread_attr_t *" attr ,
-.BI " int " inheritsched );
-.BI "int pthread_attr_getinheritsched(const pthread_attr_t *" attr ,
-.BI " int *" inheritsched );
-.sp
-Compile and link with \fI\-pthread\fP.
-.fi
-.SH DESCRIPTION
-The
-.BR pthread_attr_setinheritsched ()
-function sets the inherit-scheduler attribute of the
-thread attributes object referred to by
-.IR 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 .
-
-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)).
-
-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
-.PP
-The default setting of the inherit-scheduler attribute in
-a newly initialized thread attributes object is
-.BR PTHREAD_INHERIT_SCHED .
-
-The
-.BR pthread_attr_getinheritsched ()
-returns the inherit-scheduler attribute of the thread attributes object
-.IR 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 .
-.PP
-POSIX.1-2001 also documents an optional
-.B ENOTSUP
-error ("attempt was made to set the attribute to an unsupported value") for
-.BR pthread_attr_setinheritsched ().
-.\" .SH VERSIONS
-.\" Available since glibc 2.0.
-.SH ATTRIBUTES
-.SS Multithreading (see pthreads(7))
-The
-.BR pthread_attr_setinheritsched ()
-and
-.BR pthread_attr_getinheritsched ()
-functions are thread-safe.
-.SH CONFORMING TO
-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
-.BR 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:
-.\" http://sourceware.org/bugzilla/show_bug.cgi?id=7007

-.BR pthread_setschedparam (3).
