This group contains the Time of Day Handler implementation.
The following constants are related to the time of day and are independent of RTEMS.
This handler encapsulates functionality used to manage time of day.
◆ TOD_DAYS_PER_YEAR
#define TOD_DAYS_PER_YEAR (uint32_t)365 |
This constant represents the number of days in a non-leap year.
◆ TOD_HOURS_PER_DAY
#define TOD_HOURS_PER_DAY (uint32_t)24 |
This constant represents the number of hours per day.
◆ TOD_MICROSECONDS_PER_SECOND
#define TOD_MICROSECONDS_PER_SECOND (uint32_t)1000000 |
This constant represents the number of microseconds in a second.
◆ TOD_MILLISECONDS_PER_SECOND
#define TOD_MILLISECONDS_PER_SECOND (uint32_t)1000 |
This constant represents the number of millisecond in a second.
◆ TOD_MINUTES_PER_HOUR
#define TOD_MINUTES_PER_HOUR (uint32_t)60 |
This constant represents the number of minutes per hour.
◆ TOD_MONTHS_PER_YEAR
#define TOD_MONTHS_PER_YEAR (uint32_t)12 |
This constant represents the number of months in a year.
◆ TOD_NANOSECONDS_PER_MICROSECOND
#define TOD_NANOSECONDS_PER_MICROSECOND (uint32_t)1000 |
This constant represents the number of nanoseconds in a mircosecond.
◆ TOD_NANOSECONDS_PER_SECOND
#define TOD_NANOSECONDS_PER_SECOND (uint32_t)1000000000 |
This constant represents the number of nanoseconds in a second.
◆ TOD_SECONDS_PER_DAY
#define TOD_SECONDS_PER_DAY |
Value:
#define TOD_MINUTES_PER_HOUR
Definition: todimpl.h:76
#define TOD_SECONDS_PER_MINUTE
Definition: todimpl.h:71
#define TOD_HOURS_PER_DAY
Definition: todimpl.h:91
This constant represents the number of seconds in a day which does not include a leap second.
◆ TOD_SECONDS_PER_MINUTE
#define TOD_SECONDS_PER_MINUTE (uint32_t)60 |
This constant represents the number of seconds in a minute.
◆ TOD_SECONDS_PER_NON_LEAP_YEAR
This constant represents the number of seconds in a non-leap year.
◆ _TOD_Is_valid_new_time_of_day()
Status_Control _TOD_Is_valid_new_time_of_day |
( |
const struct timespec * |
tod | ) |
|
Checks the time point is a valid new time of day for _TOD_Set().
- Parameters
-
tod | the time of day to check. |
- Return values
-
STATUS_SUCCESSFUL | The time of day is valid. |
STATUS_INVALID_NUMBER | The time of day is invalid. |
◆ _TOD_Set()
Sets the time of day.
The caller must be the owner of the TOD lock.
- Parameters
-
tod | The new time of day in timespec format representing the time since UNIX Epoch. The new time of day shall be valid according to _TOD_Is_valid_new_time_of_day(). |
lock_context | The ISR lock context used for the corresponding _TOD_Acquire(). The caller must be the owner of the TOD lock. This function will release the TOD lock. |
- Return values
-
STATUS_SUCCESSFUL | Successful operation. |
other | Some error occurred. |
◆ _TOD_Days_to_date
const uint16_t _TOD_Days_to_date[2][13] |
|
extern |
This array contains the number of days in all months up to the month indicated by the index of the second dimension.
The first dimension should be 0 for leap years, and 1 otherwise.
