  27 .Sh DESCRIPTION
  28 The
  29 .Fn pthread_attr_get_np
  30 function provides a way to get the attributes of the thread
  31 .Fa thread
  32 after it has been created.
  33 This function is most commonly used to obtain the actual location and size of a
  34 thread's stack.
  35 .Pp
  36 The attributes pointer,
  37 .Fa attr ,
  38 will be filled in with the current attributes for the thread.
  39 The attributes should be allocated by a call to
  40 .Xr pthread_attr_init 3C
  41 prior to calling the
  42 .Fn pthrad_attr_get_np
  43 function.
  44 When
  45 .Fa attr
  46 is done being used, it should be destroyed through a call to
  47 .Xr pthread_attr_destroy 3C .
  48 .Pp
  49 The attributes of the thread
  50 .Fa thread
  51 will be the same as those passed in at the time
  52 .Xr pthread_create 3C
  53 was called (or the default set if none were specified), except that the
  54 following values will be updated:
  55 .Bl -tag -width Sy
  56 .It Sy Thread Stack Size
  57 If no explicit stack size was specified, then
  58 .Fa attr
  59 will contain the actual size of the stack.
  60 .Pp
  61 If the size of the stack was specified, then it may have been changed to
  62 ensure that the required alignment of the platform is satisfied.
