  18.      _t_a_s_k_c_t_l provides both information about tasks and the ability to control
  19.      certain attributes of a task.  _o_p_t_i_o_n specifies one of the following:
  20.  
  21.      TTTTSSSSKKKK____IIIISSSSBBBBLLLLOOOOCCCCKKKKEEEEDDDD
  22.                returns 1 if the specified task is currently blocked. Since
  23.                other processes could have subsequently unblocked the task, the
  24.                result should be considered a snapshot only.
  25.  
  26.      _t_a_s_k_c_t_l will fail if one or more of the following are true:
  27.  
  28.      [EINVAL]       _o_p_t_i_o_n does not refer to a valid option.

  30.      [EINVAL]       _t_i_d does not refer to a valid task.

  36.      Upon successful completion, _t_a_s_k_c_t_l returns a _o_p_t_i_o_n specific value.
  37.      Otherwise, a value of -1 is returned to the calling task, and _e_r_r_n_o is
  38.      set to indicate the error.
