kv_lob_get_version()

#include <kvstore.h>

kv_error_t 
kv_lob_get_version(kv_lob_handle_t *handle,
                   kv_version_t **version);

Returns the record's version. The version is owned by the handle and must not be released independently of the handle. If no version is available, KV_INVALID_ARGUMENT is returned.

The record's version is available immediately upon handle creation using kv_lob_get_for_read(). If kv_lob_get_for_write() is used, the version is available only after the LOB has been written to the store (using kv_lob_put_from_file()).

Parameters

  • handle

    The handle parameter is the LOB handle from which you want to retrieve the record's version.

  • version

    The version parameter references memory into which the value is copied. Release the resources used by this value using kv_release_version().
