Имя (Name)
sd_bus_message_sensitive - Mark a message object as containing
sensitive data
Синопсис (Synopsis)
#include <systemd/sd-bus.h>
int sd_bus_message_sensitive(sd_bus_message *message);
Описание (Description)
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.
Возвращаемое значение (Return value)
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.
