NAME
     posix_spawnattr_getschedpolicy,
     posix_spawnattr_setschedpolicy   -   get   and   set  spawn-
     schedpolicy attribute of spawn attributes object

SYNOPSIS
     #include 
     #include 

     int posix_spawnattr_getschedpolicy(
          const posix_spawnattr_t *restrict attr,
          int *restrict schedpolicy);


     int posix_spawnattr_setschedpolicy(posix_spawnattr_t *attr,
          int schedpolicy);


DESCRIPTION
     The posix_spawnattr_getschedpolicy()  function  obtains  the
     value of the spawn-schedpolicy attribute from the attributes
     object referenced by attr.


     The  posix_spawnattr_setschedpolicy()  function   sets   the
     spawn-schedpolicy  attribute  in  an  initialized attributes
     object referenced by attr.


     The spawn-schedpolicy attribute  represents  the  scheduling
     policy  to  be  assigned to the new process image in a spawn
     operation (if POSIX_SPAWN_SETSCHEDULER is set in the  spawn-
     flags  attribute).  The  default  value of this attribute is
     unspecified.

RETURN VALUES
     Upon successful completion, posix_spawnattr_getschedpolicy()
     returns  0  and  stores  the  value of the spawn-schedpolicy
     attribute of attr into the object referenced by  the  sched-
     policy  parameter. Otherwise, an error number is returned to
     indicate the error.


     Upon successful completion, posix_spawnattr_setschedpolicy()
     returns  0.  Otherwise, an error number is returned to indi-
     cate the error.

ERRORS
     These functions may fail if:

     EINVAL    The value specified by attr is invalid.
