++.Dt PTHREAD_ATTR_GET_NP 3C
++.Os
++.Sh NAME
++.Nm pthread_attr_get_np
++.Nd get pthread attributes of a running thread
++.Sh SYNOPSIS
++.In pthread.h
++.Ft int
++.Fo pthread_attr_get_np
++.Fa "pthread_t thread"
++.Fa "pthread_attr_t *attr"
++.Fc
++.Sh DESCRIPTION
++The
++.Fn pthread_attr_get_np
++function provides a way to get the attributes of the thread
++.Fa thread
++after it has been created. This function is most commonly used to obtain
++the actual location and size of a thread's stack.
++.Pp
++The attributes pointer,
++.Fa attr ,
++will be filled in with the current attributes for the thread. The
++attributes should be allocated by a call to
++.Xr pthread_attr_init 3C
++prior to calling the
++.Fn pthrad_attr_get_np
++function. When
++.Fa attr
++is done being used, it should be destroyed through a call to
++.Xr pthread_attr_destroy 3C .
++.Pp
++The attributes of the thread
++.Fa thread
++will be the same as those passed in at the time
++.Xr pthread_create 3C
++was called (or the default set if none were specified), except that the
++following values will be updated:
++.Bl -tag -width Sy
++.It Sy Thread Stack Size
++If no explicit stack size was specified, then
++.Fa attr
++will contain the actual size of the stack.
++.Pp
++If the size of the stack was specified, then it may have been changed to
++ensure that the required alignment of the platform is satisfied.
++.It Sy The Stack Address
++If no stack address was specified, then
++.Fa attr
++will contain the actual address of the stack that the system allocated
++for the thread.
++.It Sy Thread Detach State
++The detach state, whether or not the thread may be joined by a call to
++.Xr pthread_join 3C ,
++may have changed since the process was created due to a call to
++.Xr pthread_detach 3C .
++.Fa attr
++will reflect the current setting of
++.Fa thread .
++.It Sy Thread Scheduling Parameter
++The scheduling parameter attribute will be updated with the current
++scheduling parameter of
++.Fa thread .
++This is the same information as available through
++.Xr pthread_getschedparam 3C
++and it is the preferred interface for obtaining that information.
++.It Sy Thread Scheduling Policy
++The scheduling policy attribute of
++.Fa attr
++will be updated with the current scheduling policy being applied to the
++thread. This may have changed, for example, due to a call to
++.Xr pthread_setschedparam 3C .
++As with the thread's scheduling parameter, the preferred interface for
++obtaining this information is by using
++.Xr pthread_getschedparam 3C .
++.It Sy Thread Guard Size
++The value of the guard size attribute for the thread will be updated to
++reflect the actual size of the guard installed for
++.Fa thread .
++For more information on the guard size of a thread and its purpose, see
++.Xr pthread_attr_getguardsize 3C .
++.El
++.Sh RETURN VALUES
++Upon successful completion, the
++.Fn pthread_attr_get_np
++and
++.Fn pthread_getattr_np
++functions return
++.Sy 0 .
++Otherwise, an error number is returned to indicate the error.
++.Sh EXAMPLES
++The following program demonstrates how to use these functions to get
++the location and stack size of a newly created thread.
