41.Nd "get and set the spawn-schedparam attribute of a spawn attributes object"
42.Sh LIBRARY
43.Lb libc
44.Sh SYNOPSIS
45.In spawn.h
46.Ft int

49.Fn posix_spawnattr_setschedparam "posix_spawnattr_t *attr" "const struct sched_param *restrict schedparam"
50.Sh DESCRIPTION
51The
52.Fn posix_spawnattr_getschedparam
53function obtains the value of the spawn-schedparam attribute from the
54attributes object referenced by
55.Fa attr .
56.Pp
57The
58.Fn posix_spawnattr_setschedparam
59function sets the spawn-schedparam attribute in an initialized attributes
60object referenced by
61.Fa attr .
62.Pp
63The spawn-schedparam attribute represents the scheduling parameters to
64be assigned to the new process image in a spawn operation (if
65.Dv POSIX_SPAWN_SETSCHEDULER
66or
67.Dv POSIX_SPAWN_SETSCHEDPARAM
68is set in the spawn-flags attribute).
69The default value of this attribute is unspecified.
70.Sh RETURN VALUES
71The
72.Fn posix_spawnattr_getschedparam
73and
