Name: H5Fflush
Signature:
herr_t H5Fflush(hid_t object_id, H5F_scope_t scope )
Purpose:
Flushes all buffers associated with a file to disk.
Description:
H5Fflush causes all buffers associated with a file to be immediately flushed to disk without removing the data from the cache.

object_id can be any object associated with the file, including the file itself, a dataset, a group, an attribute, or a named datatype.

scope specifies whether the scope of the flushing action is global or local. Valid values are as follows:
     H5F_SCOPE_GLOBAL      Flushes the entire virtual file.
  H5F_SCOPE_LOCAL   Flushes only the specified file.

Note:
HDF5 does not possess full control over buffering. H5Fflush flushes the internal HDF5 buffers then asks the operating system (the OS) to flush the system buffers for the open files. After that, the OS is responsible for ensuring that the data is actually flushed to disk.
Parameters:
Returns:
Returns a non-negative value if successful; otherwise returns a negative value.
