Name: H5Pget_mdc_config
Signature:
herr_t H5Pget_mdc_config(hid_t plist_id, H5AC_cache_config_t *config_ptr)
Purpose:
Get the current initial metadata cache configuration from the indicated File Access Property List.
Description:
H5Pget_mdc_config gets the initial metadata cache configuration contained in a file access property list and loads it into the instance of H5AC_cache_config_t pointed to by the config_ptr parameter. This configuration is used when the file is opened.

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 guide for details on the configuration data returned. 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.
