NAME¶

sd_bus_get_name_creds, sd_bus_get_owner_creds - Query bus client credentials

SYNOPSIS¶

#include <elogind/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.

NOTES¶

Functions described here are available as a shared library, which can be compiled against and linked to with the libelogind pkg-config(8) file.

HISTORY¶

sd_bus_get_name_creds() and sd_bus_get_owner_creds() were added in version 246.
