cf.close_one_file

cf.close_one_file(file_format=None)[source]

Close an arbitrary open file containing a sub-array of a data array.

Deprecated at version 3.14.0 and is no longer available.

By default a file of arbitrary format is closed, but the choice may be restricted to files of a particular format.

Note that the closed file will be automatically reopened if subsequently needed by a variable to access the sub-array.

If there are no appropriate open files then no action is taken.

Parameters
file_format: str, optional

Only close a file of the given format. Recognised formats are 'netCDF' and 'PP'. By default a file of any format is closed.

Returns

None
