  13   15  DESCRIPTION
  14   16       The Penv_iter() function iterates over the environment of the process
  15   17       represented by P.  For each environment variable, func is passed the
  16   18       caller argument data along with the address of the environment variable
  17   19       and the key-value pair.  For the full signature of the proc_env_f

  18   20       callback, see libproc(3LIB).
  19   21  
  20   22       The callback's return value controls whether or not iteration proceeds.
  21   23       If func returns zero, then iteration continues.  Otherwise, iteration is
  22   24       terminated and the value is returned.  It is recommended that callback
  23   25       functions do not return -1 so as to distinguish between the failure of
  24   26       the Penv_iter() function and the callback function.
  25   27  
  26   28  RETURN VALUES
  27   29       Upon successful completion, the Penv_iter() function returns 0.
  28   30       Otherwise, if there was an internal error, for example due to a corrupted
  29   31       environment, then -1 is returned.  Otherwise, if the callback function
  30   32       func returns non-zero, then its return value will be returned instead.
