POSIX_SPAWNATTR_GETSCHEDPOLICY(P)   POSIX Programmer's Manual	POSIX_SPAWNATTR_GETSCHEDPOLICY(P)

NAME
       posix_spawnattr_getschedpolicy,	 posix_spawnattr_setschedpolicy   -   get   and  set  the
       spawn-schedpolicy attribute of a spawn attributes object (ADVANCED REALTIME)

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

       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 shall obtain the value of	the  spawn-sched-
       policy attribute from the attributes object referenced by attr.

       The posix_spawnattr_setschedpolicy() function shall set 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 VALUE
       Upon successful completion, posix_spawnattr_getschedpolicy() shall return zero  and  store
       the  value  of  the  spawn-schedpolicy attribute of attr into the object referenced by the
       schedpolicy parameter; otherwise, an error number shall be returned to indicate the error.

       Upon successful completion, posix_spawnattr_setschedpolicy() 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_setschedpolicy() function may fail if:

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

       The following sections are informative.

EXAMPLES
       None.

APPLICATION USAGE
       These  functions are part of the Spawn and Process Scheduling options and need not be pro-
       vided on all implementations.

RATIONALE
       None.

FUTURE DIRECTIONS
       None.
