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