sd_bus_set_method_call_timeout - Set or query the default D-Bus method call timeout of a bus object

NAME SYNOPSIS DESCRIPTION RETURN VALUE Errors NOTES SEE ALSO

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 <elogind/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

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