       sd_bus_get_fd - Get the file descriptor connected to the message bus

SYNOPSIS

       #include <systemd/sd-bus.h>

       int sd_bus_get_fd(sd_bus *bus);

DESCRIPTION

       sd_bus_get_fd() returns the file descriptor used to communicate with the message bus. This descriptor can
       be used with select(3), poll(3), or similar functions to wait for incoming messages.

       If the bus was created with the sd_bus_set_fd(3) function, then the input_fd used in that call is
       returned.

RETURN VALUE

       Returns the file descriptor used for incoming messages from the message bus.
