NAME

     posix_spawnattr_getschedparam, posix_spawnattr_setschedparam -- get and set the spawn-schedparam attribute of a spawn attributes object

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <spawn.h>

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

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

DESCRIPTION

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

     The posix_spawnattr_setschedparam() function sets 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 unspeci-
     fied.

RETURN VALUES

     The posix_spawnattr_getschedparam() and posix_spawnattr_setschedparam() functions return zero.

STANDARDS

     The posix_spawnattr_getschedparam() and posix_spawnattr_setschedparam() functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     The posix_spawnattr_getschedparam() and posix_spawnattr_setschedparam() functions first appeared in FreeBSD 8.0 and imported for NetBSD 6.

NAME

       posix_spawnattr_getschedparam, posix_spawnattr_setschedparam - get and set spawn-schedparam attribute of spawn attributes object

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 obtains the value of the spawn-schedparam attribute from the attributes object referenced by
       attr.

       The posix_spawnattr_setschedparam() function sets 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 unspeci-
       fied.

RETURN VALUES

       Upon successful completion, posix_spawnattr_getschedparam() returns 0 and stores the value of the spawn-schedparam attribute of	attr  into
       the object referenced by the schedparam parameter. Otherwise, an error number is returned to indicate the error.

       Upon successful completion, posix_spawnattr_setschedparam() returns 0. Otherwise, an error number is 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.
