SD_BUS_MESSAGE_SENSITIVE(3)d_bus_message_sensitiveD_BUS_MESSAGE_SENSITIVE(3)
sd_bus_message_sensitive - Mark a message object as containing
sensitive data
#include <systemd/sd-bus.h>
int sd_bus_message_sensitive(sd_bus_message *message);
sd_bus_message_sensitive() marks an allocated bus message as
containing sensitive data. This ensures that the message data is
carefully removed from memory (specifically, overwritten with zero
bytes) when released. It is recommended to mark all incoming and
outgoing messages like this that contain security credentials and
similar data that should be dealt with carefully. Note that it is not
possible to unmark messages like this, it's a one way operation. If a
message is already marked sensitive and then marked sensitive a
second time the message remains marked so and no further operation is
executed.
As a safety precaution all messages that are created as reply to
messages that are marked sensitive are also implicitly marked so.
On success, this functions return 0 or a positive integer. On
failure, it returns a negative errno-style error code.
Errors
Returned errors may indicate the following problems:
-EINVAL
The message parameter is NULL.
These APIs are implemented as a shared library, which can be compiled
and linked to with the libsystemd pkg-config(1) file.
