NAME
     posix_spawnattr_destroy, posix_spawnattr_init - destroy  and
     initialize spawn attributes object

SYNOPSIS
     #include 

     int posix_spawnattr_destroy(posix_spawnattr_t *attr);


     int posix_spawnattr_init(posix_spawnattr_t *attr);


DESCRIPTION
     The  posix_spawnattr_destroy()  function  destroys  a  spawn
     attributes object. A destroyed attr attributes object can be
     reinitialized using posix_spawnattr_init(). The  results  of
     otherwise referencing the object after it has been destroyed
     are    undefined.    An     implementation     can     cause
     posix_spawnattr_destroy()  to  set  the object referenced by
     attr to an invalid value.


     The  posix_spawnattr_init()  function  initializes  a  spawn
     attributes object attr with the default value for all of the
     individual attributes used by  the  implementation.  Results
     are undefined if posix_spawnattr_init() is called specifying
     an already initialized attr attributes object.


     A spawn  attributes  object  is  of  type  posix_spawnattr_t
     (defined  in  )  and is used to specify the inheri-
     tance of process attributes across a spawn operation.


     No attributes other than those defined by IEEE  Std  1003.1-
     200x are provided.


     The resulting spawn attributes object (possibly modified  by
     setting  individual attribute values), is used to modify the
     behavior of posix_spawn(3C)  or  posix_spawnp(3C).  After  a
     spawn  attributes object has been used to spawn a process by
     a call to  posix_spawn()  or  posix_spawnp(),  any  function
     affecting the attributes object (including destruction) will
     not affect any process that has been spawned in this way.

RETURN VALUES
     Upon successful  completion,  posix_spawnattr_destroy()  and
     posix_spawnattr_init()  return 0. Otherwise, an error number
     is returned to indicate the error.

     ENOMEM    Insufficient memory exists to initialize the spawn
               attributes object.



     The posix_spawnattr_destroy() function may fail if:

     EINVAL    The value specified by attr is invalid.
