NAME

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

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <spawn.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 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

     The posix_spawnattr_getschedpolicy() and posix_spawnattr_setschedpolicy() functions return zero.

STANDARDS

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

HISTORY

     The posix_spawnattr_getschedpolicy() and posix_spawnattr_setschedpolicy() functions first appeared in FreeBSD 8.0.

NAME

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

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 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 schedpolicy 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 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.
