Member Function Documentation

void ACPI_Interface::activateSettings (   )  [virtual]

activates settings for specific scheme throttling and thermal control only in ACPI Reimplemented from PM_Interface.

unsigned long ACPI_Interface::getTimestamp (   )

get time in millisecs since 1970 Returns: time in milliseconds since 1970

int ACPI_Interface::handleHWEventRequest (  int  fd = -1  )  [virtual]

Handles an event on the socket. Returns: integer value with result if handle event Return values: 1  if an event has been generated 0  if no event has been generated -1  on fatal errors -2  if acpid shuts down/ socket is missing Implements PM_Interface.

int ACPI_Interface::openAcpidSocket (   )  [virtual]

opens the socket provided by acpid Returns: the filedescriptor or < 0 on error Implements PM_Interface.

int ACPI_Interface::openHWEventFD (   )  [virtual]

opens the acpi event file Returns: the filedescriptor or -1 on error Return values: <  0 on error the  filedesctiptor on success Implements PM_Interface.

int ACPI_Interface::setBatteryAlarm_ (   )  [private]

sets the battery alarm of the current scheme Returns: integer value with the result of set batteryalarm. Also returns true if not supported Return values: -  1 on success -1  if alarm could not be set or is not supported

int ACPI_Interface::standby (   )  [virtual]

triggers execution of standby script Returns: true on success, false if not supported Implements PM_Interface.

int ACPI_Interface::suspend_to_ram (   )  [virtual]

triggers execution of suspend_to_ram script Returns: true on success, false if not supported Implements PM_Interface.

Member Data Documentation

const unsigned int ACPI_Interface::_button_time_window = 1000 [static, private]

time window for ignoring double button events

unsigned long ACPI_Interface::_last_button_occurence [private]

workaround for buggy double button events only allow one button event(sleep/power) inside the time window below (in millisecs)

string ACPI_Interface::ACPI_EVENTFILE = "/proc/acpi/event" [static]

event file for acpi events this is now configurable via -f parameter it could be either the acpid socket or the kernel acpi event file
