NAME        top

       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        top

#include <systemd/sd-bus.h>int sd_bus_set_method_call_timeout(sd_bus *bus, uint64_tusec);int sd_bus_get_method_call_timeout(sd_bus *bus, uint64_t *ret);

DESCRIPTION        top

sd_bus_set_method_call_timeout()sets the default D-Bus method       call timeout ofbus tousec microseconds.sd_bus_get_method_call_timeout()queries the default D-Bus method       call timeout ofbus. If no method call timeout was set usingsd_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, callsd_bus_set_method_call_timeout()to change the default method call       timeout.

RETURN VALUE        top

       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 parametersbus orret areNULL.           Added in version 246.-ENOPKG           Bus objectbus could not be resolved.           Added in version 246.

NOTES        top

       Functions described here are available as a shared library, which       can be compiled against and linked to with thelibsystemd pkg-config(1) file.       The code described here usesgetenv(3), which is declared to be       not multi-thread-safe. This means that the code calling the       functions described here must not callsetenv(3) from a parallel       thread. It is recommended to only do calls tosetenv()from an       early phase of the program when no other threads have been       started.

HISTORY        top
