13 posix_spawnattr_getflags, posix_spawnattr_setflags — get and set the
14 spawn-flags attribute of a spawn attributes object (ADVANCED REALTIME)
15
17 #include <spawn.h>
18
19 int posix_spawnattr_getflags(const posix_spawnattr_t *restrict attr,
20 short *restrict flags);
21 int posix_spawnattr_setflags(posix_spawnattr_t *attr, short flags);
22
24 The posix_spawnattr_getflags() function shall obtain the value of the
25 spawn-flags attribute from the attributes object referenced by attr.
26
27 The posix_spawnattr_setflags() function shall set the spawn-flags
28 attribute in an initialized attributes object referenced by attr.
29
30 The spawn-flags attribute is used to indicate which process attributes
31 are to be changed in the new process image when invoking posix_spawn()
32 or posix_spawnp(). It is the bitwise-inclusive OR of zero or more of
33 the following flags:
34
35 POSIX_SPAWN_RESETIDS
36 POSIX_SPAWN_SETPGROUP
37 POSIX_SPAWN_SETSIGDEF
38 POSIX_SPAWN_SETSIGMASK
39 POSIX_SPAWN_SETSCHEDPARAM
40 POSIX_SPAWN_SETSCHEDULER
41
42 These flags are defined in <spawn.h>. The default value of this
43 attribute shall be as if no flags were set.
44
46 Upon successful completion, posix_spawnattr_getflags() shall return
47 zero and store the value of the spawn-flags attribute of attr into the
48 object referenced by the flags parameter; otherwise, an error number
49 shall be returned to indicate the error.
50
51 Upon successful completion, posix_spawnattr_setflags() shall return
52 zero; otherwise, an error number shall be returned to indicate the
53 error.
54
56 These functions may fail if:
57
58 EINVAL The value specified by attr is invalid.
59
60 The posix_spawnattr_setflags() function may fail if:
61
62 EINVAL The value of the attribute being set is not valid.
63
64 The following sections are informative.
65
67 None.
68
70 These functions are part of the Spawn option and need not be provided
71 on all implementations.
72
74 None.
75
77 None.
