Where the fields of the instance of H5AC_cache_image_config_t passed into the function will be set as follows:
Must be set to H5AC__CURR_CACHE_IMAGE_CONFIG_VERSION prior to the call to H5Pget_mdc_image_config()
Will be set to either 1 (TRUE) or 0 (FALSE), depending on whether a cache image will be requested
Will be set to either 1 (TRUE) or 0 (FALSE), depending on whether inclusion of the metadata cache resize configuration is to be included in the cache image. Note that this field is not supported at present.
Will be set to an integer in the range of -1 to 100. Non negative values indicate the number of close/open cycles a metadata cache can remain in the cache image without being accessed. -1 indicates no limit on the number of such cycles. Note: this field is not supported at present -- thus in effect it is always set to -1.
Returns a non-negative value if successful; otherwise returns a negative value.
