ИМЯ

       sd_bus_get_name_creds, sd_bus_get_owner_creds - Query bus client
       credentials

СИНТАКСИС

       #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);

ОПИСАНИЕ

       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().

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       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, library or module
           instance.

       -ENOMEM
           Memory allocation failed.

ПРИМЕЧАНИЯ

       Functions described here are available as a shared library, which
       can be compiled against and linked to with the
       libsystemd pkg-config(1) file.

       The code described here uses getenv(3), which is declared to be
       not multi-thread-safe. This means that the code calling the
       functions described here must not call setenv(3) from a parallel
       thread. It is recommended to only do calls to setenv() from an
       early phase of the program when no other threads have been
       started.

ИСТОРИЯ

       sd_bus_get_name_creds() and sd_bus_get_owner_creds() were added
       in version 221.
