Data Fields | |
| uint64_t | capacity |
| Maximum capacity (in octets) of the flash journal--i.e. the largest 'blob' which can be contained as payload. | |
| uint64_t | sizeofJournaledBlob |
| size (in octets) of the most recently logged blob. | |
| uint32_t | program_unit |
| Minimum programming size (in units of octets) for the current storage block--the one which will be used for the next log() operation. | |

Field Documentation
| uint64_t capacity |
Maximum capacity (in octets) of the flash journal--i.e. the largest 'blob' which can be contained as payload.
Definition at line 70 of file flash_journal.h.
| uint32_t program_unit |
Minimum programming size (in units of octets) for the current storage block--the one which will be used for the next log() operation.
This value may change as we cycle through the blocks of the underlying MTD. Callers of FlashJournal_log() should refer to this field upon receiving the error JOURNAL_STATUS_SMALL_LOG_REQUEST (of when the actual amount of data logged is smaller than the requested amount).
Definition at line 72 of file flash_journal.h.
| uint64_t sizeofJournaledBlob |
size (in octets) of the most recently logged blob.
Definition at line 71 of file flash_journal.h.
