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.

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