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.
