sd_bus_set_method_call_timeout(3) — Linux manual page



NAME         top

       sd_bus_set_method_call_timeout, sd_bus_get_method_call_timeout -
       Set or query the default D-Bus method call timeout of a bus

SYNOPSIS         top

       #include <systemd/sd-bus.h>

       int sd_bus_set_method_call_timeout(sd_bus *bus, uint64_t usec);

       int sd_bus_get_method_call_timeout(sd_bus *bus, uint64_t *ret);

DESCRIPTION         top

       sd_bus_set_method_call_timeout() sets the default D-Bus method
       call timeout of bus to usec microseconds.

       sd_bus_get_method_call_timeout() queries the default D-Bus method
       call timeout of bus. If no method call timeout was set using
       sd_bus_set_method_call_timeout(), the timeout is read from the
       $SYSTEMD_BUS_TIMEOUT environment variable. If this environment
       variable is unset or does not contain a valid timeout, the
       implementation falls back to a predefined method call timeout of
       25 seconds. Note that $SYSTEMD_BUS_TIMEOUT is read once and
       cached so callers should not rely on being able to change the
       default method call timeout at runtime by changing the value of
       $SYSTEMD_BUS_TIMEOUT. Instead, call
       sd_bus_set_method_call_timeout() to change the default method
       call timeout.

RETURN VALUE         top

       On success, these functions return a non-negative integer. On
       failure, they return a negative errno-style error code.

       Returned errors may indicate the following problems:

           The parameters bus or ret are NULL.

           Bus object bus could not be resolved.

NOTES         top

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