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.
