SD_BUS_GET_NAME_CREDS(3) sd_bus_get_name_creds SD_BUS_GET_NAME_CREDS(3)
NAME
sd_bus_get_name_creds, sd_bus_get_owner_creds - Query bus client
credentials
SYNOPSIS
#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
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().
RETURN VALUE
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.
NOTES
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.
