43.Nd "get and set the spawn-schedparam attribute of a spawn attributes object"
44.Sh LIBRARY
45.Lb libc
46.Sh SYNOPSIS
47.In spawn.h
48.Ft int
49.Fn posix_spawnattr_getschedparam "const posix_spawnattr_t *restrict attr" "struct sched_param *restrict schedparam"
50.Ft int
51.Fn posix_spawnattr_setschedparam "posix_spawnattr_t *attr" "const struct sched_param *restrict schedparam"
52.Sh DESCRIPTION
53The
54.Fn posix_spawnattr_getschedparam
55function obtains the value of the spawn-schedparam attribute from the
56attributes object referenced by
57.Fa attr .
58.Pp
59The
60.Fn posix_spawnattr_setschedparam
61function sets the spawn-schedparam attribute in an initialized attributes
62object referenced by
63.Fa attr .
64.Pp
65The spawn-schedparam attribute represents the scheduling parameters to
66be assigned to the new process image in a spawn operation (if
67.Dv POSIX_SPAWN_SETSCHEDULER
68or
69.Dv POSIX_SPAWN_SETSCHEDPARAM
70is set in the spawn-flags attribute).
71The default value of this attribute is unspecified.
72.Sh RETURN VALUES
73The
74.Fn posix_spawnattr_getschedparam
75and
76.Fn posix_spawnattr_setschedparam
77functions return zero.
