NAME

       sd_bus_get_current_handler, sd_bus_get_current_message, sd_bus_get_current_slot,
       sd_bus_get_current_userdata - Query information of the callback a bus object is currently
       running

SYNOPSIS

       #include <systemd/sd-bus.h>

       typedef int (*sd_bus_message_handler_t)(sd_bus_message *m, void *userdata,
                                               sd_bus_error *ret_error);

       sd_bus_message_handler_t sd_bus_get_current_handler(sd_bus *bus);

       sd_bus_message* sd_bus_get_current_message(sd_bus *bus);

       sd_bus_slot* sd_bus_get_current_slot(sd_bus *bus);

       void* sd_bus_get_current_userdata(sd_bus *bus);

DESCRIPTION

       Whenever sd-bus is about to invoke a user-supplied callback function, it stores the
       current callback, D-Bus message, slot and userdata pointer and allows these to be queried
       via sd_bus_get_current_handler(), sd_bus_get_current_message(), sd_bus_get_current_slot()
       and sd_bus_get_current_userdata(), respectively. If bus cannot be resolved or if execution
       does not reside in a user-supplied callback of bus, these functions return NULL.

RETURN VALUE

       On success, these functions return the requested object. On failure, they return NULL.

NOTES

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