NAME

6       sd_bus_message_sensitive - Mark a message object as containing
7       sensitive data
8

SYNOPSIS

10       #include <systemd/sd-bus.h>
11
12       int sd_bus_message_sensitive(sd_bus_message *message);
13

DESCRIPTION

15       sd_bus_message_sensitive() marks an allocated bus message as containing
16       sensitive data. This ensures that the message data is carefully removed
17       from memory (specifically, overwritten with zero bytes) when released.
18       It is recommended to mark all incoming and outgoing messages like this
19       that contain security credentials and similar data that should be dealt
20       with carefully. Note that it is not possible to unmark messages like
21       this, it's a one way operation. If a message is already marked
22       sensitive and then marked sensitive a second time the message remains
23       marked so and no further operation is executed.
24
25       As a safety precaution all messages that are created as reply to
26       messages that are marked sensitive are also implicitly marked so.

RETURN VALUE

29       On success, this functions return 0 or a positive integer. On failure,
30       it returns a negative errno-style error code.
31
32   Errors
33       Returned errors may indicate the following problems:
34
35       -EINVAL
36           The message parameter is NULL.
