6 posix_spawnattr_getflags, posix_spawnattr_setflags - get and set the
7 spawn-flags attribute of a spawn attributes object (ADVANCED REALTIME)

10 #include <spawn.h>
11
12 int posix_spawnattr_getflags(const posix_spawnattr_t *restrict attr,
13 short *restrict flags);
14 int posix_spawnattr_setflags(posix_spawnattr_t *attr, short flags);
15
16
18 The posix_spawnattr_getflags() function shall obtain the value of the
19 spawn-flags attribute from the attributes object referenced by attr.
20
21 The posix_spawnattr_setflags() function shall set the spawn-flags
22 attribute in an initialized attributes object referenced by attr.
23
24 The spawn-flags attribute is used to indicate which process attributes
25 are to be changed in the new process image when invoking posix_spawn()
26 or posix_spawnp(). It is the bitwise-inclusive OR of zero or more of
27 the following flags:
28
29 POSIX_SPAWN_RESETIDS
30 POSIX_SPAWN_SETPGROUP
31 POSIX_SPAWN_SETSIGDEF
32 POSIX_SPAWN_SETSIGMASK
33
34 POSIX_SPAWN_SETSCHEDPARAM
35 POSIX_SPAWN_SETSCHEDULER
36
37
38 These flags are defined in <spawn.h>. The default value of this
39 attribute shall be as if no flags were set.
40
42 Upon successful completion, posix_spawnattr_getflags() shall return
43 zero and store the value of the spawn-flags attribute of attr into the
44 object referenced by the flags parameter; otherwise, an error number
45 shall be returned to indicate the error.
46
47 Upon successful completion, posix_spawnattr_setflags() shall return
48 zero; otherwise, an error number shall be returned to indicate the
49 error.
50
52 These functions may fail if:
53
54 EINVAL The value specified by attr is invalid.
55
56
57 The posix_spawnattr_setflags() function may fail if:
58
59 EINVAL The value of the attribute being set is not valid.
