NAME         top

       sd_bus_get_name_creds, sd_bus_get_owner_creds - Query bus client

SYNOPSIS         top

       #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);

DESCRIPTION         top

       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_get_owner_creds() queries the credentials of the creator of
       the given bus. The mask and creds parameters behave the same as in

RETURN VALUE         top

       On success, these functions return a non-negative integer. On
       failure, they return a negative errno-style error code.

       Returned errors may indicate the following problems:

           An argument is invalid.

           The bus cannot be resolved.

           The bus has already been started.

           The bus was created in a different process.

           Memory allocation failed.

NOTES         top

       These APIs are implemented as a shared library, which can be compiled
       and linked to with the libsystemd pkg-config(1) file.
