SD_BUS_SET_METHOD_CALL_Tsd_bus_set_method_calSD_BUS_SET_METHOD_CALL_TIMEOUT(3)
NAME
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
SYNOPSIS
#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);
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.
NOTES
Functions described here are available as a shared library, which can
be compiled against and linked to with the libsystemd pkg-config(1)
file.
The code described here uses getenv(3), which is declared to be not
multi-thread-safe. This means that the code calling the functions
described here must not call setenv(3) from a parallel thread. It is
recommended to only do calls to setenv() from an early phase of the
program when no other threads have been started.
