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.
