SD_BUS_SET_METHOD_CALL_TIMEOUT(3)ethod_call_timeoutETHOD_CALL_TIMEOUT(3)
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
#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);
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.
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.
These APIs are implemented as a shared library, which can be
compiled and linked to with the libsystemd pkg-config(1) file.
