Name: H5Fget_mdc_config
Signature:
herr_t H5Fget_mdc_config(hid_t file_id, H5AC_cache_config_t *config_ptr)
Purpose:
Obtain current metadata cache configuration for target file.
Description:
H5Fget_mdc_config loads the current metadata cache configuration into the instance of H5AC_cache_config_t pointed to by the config_ptr parameter.

Note that the version field of *config_ptr must be initialized --this allows the library to support old versions of the H5AC_cache_config_t structure.

See the overview of the metadata cache in the special topics section of the user manual for details on metadata cache configuration. If you haven't read and understood that documentation, the results of this call will not make much sense.

Parameters:
Returns:
Returns a non-negative value if successful; otherwise returns a negative value.
