SD_BUS_GET_NAME_CREDS(3) sd_bus_get_name_creds SD_BUS_GET_NAME_CREDS(3)
sd_bus_get_name_creds, sd_bus_get_owner_creds - Query bus client
credentials
#include <systemd/sd-bus.h>
int sd_bus_get_name_creds(sd_bus *bus, const char *name,
uint64_t mask, sd_bus_creds **creds);
int sd_bus_get_owner_creds(sd_bus *bus, uint64_t mask,
sd_bus_creds **creds);
sd_bus_get_name_creds() queries the credentials of the bus client
identified by name. The mask parameter is a combo of SD_BUS_CREDS_*
flags that indicate which credential info the caller is interested
in. See sd_bus_creds_new_from_pid(3) for a list of possible flags. On
success, creds contains a new sd_bus_creds instance with the
requested information. Ownership of this instance belongs to the
caller and it should be freed once no longer needed by calling
sd_bus_creds_unref(3).
sd_bus_get_owner_creds() queries the credentials of the creator of
the given bus. The mask and creds parameters behave the same as in
sd_bus_get_name_creds().
On success, these functions return a non-negative integer. On
failure, they return a negative errno-style error code.
Errors
Returned errors may indicate the following problems:
-EINVAL
An argument is invalid.
-ENOPKG
The bus cannot be resolved.
-EPERM
The bus has already been started.
-ECHILD
The bus was created in a different process.
-ENOMEM
Memory allocation failed.
These APIs are implemented as a shared library, which can be compiled
and linked to with the libsystemd pkg-config(1) file.
