NAME

6       sd_bus_set_method_call_timeout, sd_bus_get_method_call_timeout - Set or
7       query the default D-Bus method call timeout of a bus object
8

SYNOPSIS

10       #include <systemd/sd-bus.h>
11
12       int sd_bus_set_method_call_timeout(sd_bus *bus, uint64_t usec);
13
14       int sd_bus_get_method_call_timeout(sd_bus *bus, uint64_t *ret);
15

DESCRIPTION

17       sd_bus_set_method_call_timeout() sets the default D-Bus method call
18       timeout of bus to usec microseconds.
19
20       sd_bus_get_method_call_timeout() queries the default D-Bus method call
21       timeout of bus. If no method call timeout was set using
22       sd_bus_set_method_call_timeout(), the timeout is read from the
23       $SYSTEMD_BUS_TIMEOUT environment variable. If this environment variable
24       is unset or does not contain a valid timeout, the implementation falls
25       back to a predefined method call timeout of 25 seconds. Note that
26       $SYSTEMD_BUS_TIMEOUT is read once and cached so callers should not rely
27       on being able to change the default method call timeout at runtime by
28       changing the value of $SYSTEMD_BUS_TIMEOUT. Instead, call
29       sd_bus_set_method_call_timeout() to change the default method call
30       timeout.

RETURN VALUE

33       On success, these functions return a non-negative integer. On failure,
34       they return a negative errno-style error code.
35
36   Errors
37       Returned errors may indicate the following problems:
38
39       -EINVAL
40           The parameters bus or ret are NULL.
41
42       -ENOPKG
43           Bus object bus could not be resolved.

NOTES

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