  22.      The _c_p_u_s_e_t_A_t_t_a_c_h_P_I_D function is used to attach a specific process
  23.      identified by its PID to the cpuset identified by _qqqq_nnnn_aaaa_mmmm_eeee.  Every cpuset
  24.      queue has a file that defines access permissions to the queue.  The
  25.      execute permissions for that file will determine if a process owned by a
  26.      specific user can attach a process to the cpuset queue.
  27.  
  28.      The _qqqq_nnnn_aaaa_mmmm_eeee argument is the name of the cpuset to which the specified
  29.      process should be attached.

  32.      This example attaches the current process to a cpuset queue named
  33.      mpi_set.
  34.  
  35.                char *qname = "mpi_set";
  36.  
  37.                /* Attach to cpuset, if error - print error & exit */
  38.                if (!cpusetAttachPID(qname, pid)) {
  39.                    perror("cpusetAttachPID");
  40.                    exit(1);

  45.      _c_p_u_s_e_t_A_t_t_a_c_h_P_I_D is found in the library "libcpuset.so", and will be
  46.      loaded if the option _----_llll_cccc_pppp_uuuu_ssss_eeee_tttt is used with _cccc_cccc(1) or _llll_dddd(1).

  52.      If successful, _c_p_u_s_e_t_A_t_t_a_c_h_P_I_D returns a 1.  If _c_p_u_s_e_t_A_t_t_a_c_h_P_I_D fails, it
  53.      returns the value 0 and eeeerrrrrrrrnnnnoooo is set to indicate the error.  The possible
  54.      values for eeeerrrrrrrrnnnnoooo are the same as those used by _s_y_s_m_p(2).
