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 .

Added in version 246.

-ENOPKG

Bus object bus could not be resolved.

Added in version 246.

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.

HISTORY

sd_bus_set_method_call_timeout() and sd_bus_get_method_call_timeout() were added in version 246.
