herr_t H5Odisable_mdc_flushes( hid_t object_id )
H5Xflush()functions can be used to control the flushing of entries from a file’s metadata cache.
This function prevents an object’s or cache’s
dirty metadata entries from being flushed from the cache by the usual
cache eviction/flush policy. Instead, users must manually flush
the cache or entries for individual objects via the appropriate
Metadata cache entries can be controlled at both the individual HDF5 object level (datasets, groups, committed datatypes) and the entire metadata cache level.
hid_tidentifiers that represent these objects can be passed to this function.
Passing in a
hid_t identifier that represents any
other HDF5 entity is considered an error.
It is an error to pass an HDF5 file identifier (obtained from
H5Fcreate()) to this function.
Misuse of this function can cause the cache to exhaust available memory.
Objects can be returned to the default automatic flush behavior
Flush prevention only pertains to new or dirty metadata entries. Clean entries can be evicted from the cache.
Calling this function on an object that has already had flushes disabled will return an error.
||IN: Identifier of the object that will have flushes
