* Function: H5Fstart_swmr_write
*
* Purpose: To enable SWMR writing mode for the file
- * 1) Refresh opened objects: part 1
- * 2) Flush & reset accumulator
- * 3) Mark the file in SWMR writing mode
- * 4) Set metadata read attempts and retries info
- * 5) Disable accumulator
- * 6) Evict all cache entries except the superblock
- * 7) Refresh opened objects (part 2)
- * 8) Unlock the file
- *
- * Pre-conditions:
- * 1) The file being opened has v3 superblock
- * 2) The file is opened with H5F_ACC_RDWR
- * 3) The file is not already marked for SWMR writing
- * 4) Current implementaion for opened objects:
- * --only allow datasets and groups without attributes
- * --disallow named datatype with/without attributes
- * --disallow opened attributes attached to objects
- * NOTE: Currently, only opened groups and datasets are allowed
- * when enabling SWMR via H5Fstart_swmr_write().
- * Will later implement a different approach--
- * set up flush dependency/proxy even for file opened without
- * SWMR to resolve issues with opened objects.
*
* Return: Non-negative on success/negative on failure
