herr_t H5Oenable_mdc_flushes(
hid_t object_id
)H5O/H5Fenable/disable_mdc_flushes() and associated
H5Xflush() functions can be used to control the flushing
of entries from a file’s metadata cache.
This function allows an object or cache’s dirty metadata entries to be flushed from the cache by the usual cache eviction/flush policy.
Metadata cache entries can be controlled at both the individual HDF5 object level (datasets, groups, committed datatypes) and the entire metadata cache level.
hid_t identifiers that represent these objects
can be passed to the function.
Passing in an 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
H5Fopen() or H5Fcreate()) to this function.
Use H5Fenable_mdc_flushes instead.
Using this function on an object that has not had flushes disabled
is considered an error. The state of an object can be determined with
H5Oare_flushes_disabled().
Individual objects can be returned to the default flush algorithm
with this function after H5Fdisable_mdc_flushes() has
been used to globally prevent flushes.
An object will be returned to the default flush algorithm when it is closed.
All objects will be returned to the default flush algorithm when the file is closed.
An object’s entries will not necessarily be flushed as a result of calling this function.
