BACnetStack_RegisterCallbackWriteFileRecord

void BACnetStack_RegisterCallbackWriteFileRecord(
  bool (*FPCallbackWriteFileRecord)(const uint32_t deviceInstance, const uint32_t fileInstance, const int32_t fileStartRecord, const uint32_t recordCount, const uint8_t *recordData, const uint32_t *recordDataLengths, int32_t *ackFileStartRecord, uint32_t *errorCode));

Registers a callback to handle write file requests against File objects whose File_Access_Method is record access.

The callback will be called in response to an AtomicWriteFile BACnet message.

Note

Requires one of the build options STACK_OPTION_NM_SCCM_A (with the BACnet/SC data link), STACK_OPTION_DM_BR_BACKUP_AND_RESTORE (any of them turns on STACK_OPTION_ATOMIC_FILE_IO, the macro this function checks).
