Function Documentation

◆ DATA_DatabaseEntryUpdatedAtLeastOnce()

bool DATA_DatabaseEntryUpdatedAtLeastOnce ( void *  pDatabaseEntry)

Checks if passed database entry has been updated at least once.

Parameters
[in]pDatabaseEntry(type: void *)
Returns
true if database entry has been updated at least once, otherwise false

Definition at line 328 of file database.c.

◆ DATA_DatabaseEntryUpdatedRecently()

bool DATA_DatabaseEntryUpdatedRecently ( void *  pDatabaseEntry,
uint32_t  timeInterval 
)

Checks if passed database entry has been updated within the last time interval.

Parameters
[in]pDatabaseEntry(type: void *)
[in]timeIntervalin systicks (type: uint32_t)
Returns
true if database entry has been updated within the time interval, otherwise false

Definition at line 340 of file database.c.

Here is the call graph for this function:

◆ DATA_DatabaseEntryUpdatedWithinInterval()

bool DATA_DatabaseEntryUpdatedWithinInterval ( void *  pDatabaseEntry,
uint32_t  timeInterval 
)

Checks if passed database entry has been periodically updated within the time interval.

Checks if the last update timestamp is not older than time interval and if the difference between previous timestamp and timestamp is smaller than time interval

Parameters
[in]pDatabaseEntry(type: void *)
[in]timeIntervalin systicks (type: uint32_t)
Returns
true if database entry has been periodically updated within the time interval, otherwise false

Definition at line 356 of file database.c.

Here is the call graph for this function:

◆ DATA_DummyFunction()

void DATA_DummyFunction ( void  )

Dummy void function of the database module.

This function is needed in the database module in order to implement the DATA_READ_DATA() and DATA_WRITE_DATA() in a ISO C99 standard compatible way. The invocation of a macro that accepts a variable number of arguments (and this is the case for DATA_READ_DATA() and DATA_WRITE_DATA()) needs more arguments in the invocation than there are parameters in the macro definition. For the most simple case, that DATA_READ_DATA() and DATA_WRITE_DATA() are only called with one argument, a violation of the standard would appear if the DATA_DummyFunction() would be omitted: GET_MACRO(databaseVaribale, DATA_Read_4_DataBlocks, DATA_Read_3_DataBlocks, DATA_Read_2_DataBlocks, DATA_Read_2_DataBlocks, DATA_Read_1_DataBlock)(databaseVaribale) So the macro invocation has six parameters, but it needs seven and an ISO C99 violation would appear. Adding the DATA_DummyFunction() fixes this violation. For details see 6.10.3 (paragraph 4) of the ISO C99 standard.
