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 object
sd_bus_set_method_call_timeout() sets the default D-Bus method call
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.
On success, these functions return a non-negative integer. On failure, they return a negative errno-style error code.
