46.Sh SYNOPSIS
47.In spawn.h
48.Ft int
49.Fn posix_spawnattr_getflags "const posix_spawnattr_t *restrict attr" "short *restrict flags"
50.Ft int
51.Fn posix_spawnattr_setflags "posix_spawnattr_t *attr" "short flags"
52.Sh DESCRIPTION
53The
54.Fn posix_spawnattr_getflags
55function obtains the value of the spawn-flags attribute from the
56attributes object referenced by
57.Fa attr .
58.Pp
59The
60.Fn posix_spawnattr_setflags
61function sets the spawn-flags attribute in an initialized
62attributes object referenced by
63.Fa attr .
64.Pp
65The spawn-flags attribute is used to indicate which process attributes
66are to be changed in the new process image when invoking
67.Fn posix_spawn
68or
69.Fn posix_spawnp .
70It is the bitwise-inclusive OR of zero or more of the following flags
71(see
72.Fn posix_spawn ) :
73.Bl -tag -offset indent
74.It Dv POSIX_SPAWN_RESETIDS
75.It Dv POSIX_SPAWN_SETPGROUP
76.It Dv POSIX_SPAWN_SETSIGDEF
77.It Dv POSIX_SPAWN_SETSIGMASK
78.It Dv POSIX_SPAWN_SETSCHEDPARAM
79.It Dv POSIX_SPAWN_SETSCHEDULER
