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.
