rtems_device_driver | rtc_control (rtems_device_major_number, rtems_device_minor_number, void *) |
This driver interface provides support to read and set the real-time clock and to initialize the time of day for the system.
#define RTC_DEVICE_NAME "/dev/rtc" |
Device file name path.
#define RTC_DRIVER_TABLE_ENTRY |
Device driver table entry.
rtems_device_driver rtc_close | ( | rtems_device_major_number | , |
rtems_device_minor_number | , | ||
void * | |||
) |
Closes the real-time clock device.
rtems_device_driver rtc_control | ( | rtems_device_major_number | , |
rtems_device_minor_number | , | ||
void * | |||
) |
Controls the real-time clock.
rtems_device_driver rtc_initialize | ( | rtems_device_major_number | , |
rtems_device_minor_number | , | ||
void * | |||
) |
Initializes the real-time clock device and sets the time of day for the system.
If the real-time clock provides an invalid time of day value the system time of day must remain untouched.
rtems_device_driver rtc_open | ( | rtems_device_major_number | , |
rtems_device_minor_number | , | ||
void * | |||
) |
Opens the real-time clock device.
rtems_device_driver rtc_read | ( | rtems_device_major_number | , |
rtems_device_minor_number | , | ||
void * | |||
) |
Reads the real-time clock value.
The value will be returned in a rtems_time_of_day structure.
rtems_device_driver rtc_write | ( | rtems_device_major_number | , |
rtems_device_minor_number | , | ||
void * | |||
) |
Sets the real-time clock value.
The value will be set from a rtems_time_of_day structure.
