posix_spawnattr_setschedparam

       set  the  spawn-schedparam  attribute  of  a  spawn  attributes  object
       (ADVANCED REALTIME)

SYNOPSIS
       #include <spawn.h>
       #include <sched.h>

       int posix_spawnattr_getschedparam(const posix_spawnattr_t *
              restrict attr, struct sched_param *restrict schedparam);
       int posix_spawnattr_setschedparam(posix_spawnattr_t *restrict attr,
              const struct sched_param *restrict schedparam);


DESCRIPTION
       The  posix_spawnattr_getschedparam() function shall obtain the value of
       the spawn-schedparam attribute from the attributes object referenced by
       attr.

       The posix_spawnattr_setschedparam() function shall set the spawn-sched-
       param attribute in an initialized attributes object referenced by attr.

       The spawn-schedparam attribute represents the scheduling parameters  to
       be  assigned  to  the  new  process  image  in  a  spawn  operation (if
       POSIX_SPAWN_SETSCHEDULER or POSIX_SPAWN_SETSCHEDPARAM  is  set  in  the
       spawn-flags attribute). The default value of this attribute is unspeci-
       fied.

RETURN VALUE
       Upon  successful  completion,   posix_spawnattr_getschedparam()   shall
       return  zero  and  store the value of the spawn-schedparam attribute of
       attr into the object referenced by the schedparam parameter; otherwise,
       an error number shall be returned to indicate the error.

       Upon   successful   completion,  posix_spawnattr_setschedparam()  shall
       return zero; otherwise, an error number shall be returned  to  indicate
       the error.

ERRORS
       These functions may fail if:

       EINVAL The value specified by attr is invalid.


       The posix_spawnattr_setschedparam() function may fail if:

       EINVAL The value of the attribute being set is not valid.
