## Description

`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

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

### Errors

Returned errors may indicate the following problems:

`-EINVAL`

  The parameters bus or ret are `NULL`.

`-ENOPKG`

  Bus object bus could not be resolved.

## History

`sd_bus_set_method_call_timeout()` and `sd_bus_get_method_call_timeout()` were added in version 246.
