.SH DESCRIPTION |
|
24 |
.LP
|
|
25 |
The \fIposix_spawn_file_actions_destroy\fP() function shall destroy |
|
26 |
the object referenced by \fIfile_actions\fP; the object |
|
27 |
becomes, in effect, uninitialized. An implementation may cause \fIposix_spawn_file_actions_destroy\fP() |
|
28 |
to set the object |
|
29 |
referenced by \fIfile_actions\fP to an invalid value. A destroyed |
|
30 |
spawn file actions object can be reinitialized using |
|
31 |
\fIposix_spawn_file_actions_init\fP(); the results of otherwise referencing |
|
32 |
the object after it has been destroyed are |
|
33 |
undefined. |
|
34 |
.LP
|
|
35 |
The \fIposix_spawn_file_actions_init\fP() function shall initialize |
|
36 |
the object referenced by \fIfile_actions\fP to contain no |
|
37 |
file actions for \fIposix_spawn\fP() or \fIposix_spawnp\fP() to perform. |
|
38 |
.LP
|
|
39 |
A spawn file actions object is as defined in \fIposix_spawn_file_actions_addclose\fP() |
|
40 |
\&.
|
|
41 |
.LP
|
|
42 |
The effect of initializing an already initialized spawn file actions |
|
43 |
object is undefined. |
|
44 |
.SH RETURN VALUE |
|
45 |
.LP
|
|
46 |
Upon successful completion, these functions shall return zero; otherwise, |
|
47 |
an error number shall be returned to indicate the |
|
48 |
error. |
|
49 |
.SH ERRORS |
|
50 |
.LP
|
|
51 |
The \fIposix_spawn_file_actions_init\fP() function shall fail if: |
|
52 |
.TP 7 |
|
53 |
.B ENOMEM |
|
54 |
Insufficient memory exists to initialize the spawn file actions object. |
|

The \fIposix_spawn_file_actions_destroy\fP() function may fail if: |
|
58 |
.TP 7 |
|
59 |
.B EINVAL |
|
60 |
The value specified by \fIfile_actions\fP is invalid. |
