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

NAME
       posix_spawnattr_getschedparam,	posix_spawnattr_setschedparam	-   get   and	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-sched-
       param attribute from the attributes object referenced by attr.

       The  posix_spawnattr_setschedparam()  function shall set the spawn-schedparam 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 unspecified.

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.

       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.
