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 unspecified.
