.Dd May 10, 2013 .Dt PTHREAD_ATTR_GETINHERITSCHED 3 .Os .Sh NAME .Nm pthread_attr_getinheritsched , .Nm pthread_attr_setinheritsched .Nd get and set .Dq inheritsched attribute .Sh LIBRARY .Lb libpthread .Sh SYNOPSIS n pthread.h .Ft int .Fn pthread_attr_getinheritsched \ "const pthread_attr_t * restrict attr" "int * restrict inheritsched" .Ft int .Fn pthread_attr_setinheritsched "pthread_attr_t *attr" "int inheritsched" .Sh DESCRIPTION The .Fn pthread_attr_getinheritsched and .Fn pthread_attr_setinheritsched functions get and set, respectively, the inherit scheduler attribute, .Fa inheritsched , in the .Fa attr object. The .Fa inheritsched parameter specifies whether a thread created by using .Fa attr will obtain its scheduling attributes directly from .Fa attr or whether it will inherit these from the calling thread.
p Two values are possible for .Fa inheritsched : l -tag -width PTHREAD_EXPLICIT_SCHED -offset indent t Dv PTHREAD_INHERIT_SCHED The thread scheduling attributes will be inherited from the creating thread and the ones in .Fa attr are ignored. t Dv PTHREAD_EXPLICIT_SCHED The thread scheduling attributes will be set to the corresponding values in .Fa attr . .El
p The following thread scheduling attributes are affected by .Fa inheritsched : l -bullet -offset indent t Scheduling policy; see .Xr pthread_attr_setschedpolicy 3 . t Scheduling parameter; see .Xr pthread_attr_getschedparam 3 . t Scheduling contention scope; see .Xr pthread_attr_getscope 3 . .El .Sh RETURN VALUES If successful, both functions return 0. Otherwise, an error number is returned to indicate the error. .Sh COMPATIBILITY The standard leaves it unspecified which (if any) is the default inherit scheduler attribute in a newly initialized attribute object. .Sh ERRORS No errors are defined for .Fn pthread_attr_getinheritsched .
p The .Fn pthread_attr_setinheritsched function may fail if: l -tag -width Er t Bq Er EINVAL The value specified by .Fa inheritsched is invalid. .El .Sh SEE ALSO .Xr pthread_attr 3 .Sh STANDARDS Both functions conform to .St -p1003.1-2008 .
