#include <flash_journal.h>
Data Fields | |
| uint32_t | version |
| Journal-header specific magic code. | |
| uint64_t | totalSize |
| Revision number for this generic journal header. | |
| uint32_t | sizeofHeader |
| Total space (in bytes) occupied by the journal, including the header. | |
| uint32_t | journalOffset |
| The size of the journal header; this is expected to be larger than this generic header. | |
| uint32_t | checksum |
| Offset from the start of the journal header to the actual logged journal. | |
Detailed Description
Meta-data placed at the head of a Journal.
The actual header would be an extension of this generic header, and would depend on the implementation strategy. Initialization algorithms can expect to find this generic header at the start of every Journal.

Field Documentation
| uint32_t checksum |
Offset from the start of the journal header to the actual logged journal.
Definition at line 101 of file flash_journal.h.
| uint32_t journalOffset |
The size of the journal header; this is expected to be larger than this generic header.
Definition at line 100 of file flash_journal.h.
| uint32_t sizeofHeader |
Total space (in bytes) occupied by the journal, including the header.
Both 'mtdOffset' and 'mtdOffset + totalSize' should lie on erase boundaries.
Definition at line 99 of file flash_journal.h.
| uint64_t totalSize |
Revision number for this generic journal header.
Definition at line 96 of file flash_journal.h.
| uint32_t version |
Journal-header specific magic code.
Definition at line 95 of file flash_journal.h.
