DESCRIPTION

       The  pmem2_config_set_length()  function  configures  the length which will be used for mapping.  *config
       should be already initialized, please see pmem2_config_new(3) for details.  The must be a multiple of the
       alignment required for the data source which will be used for mapping alongside the config.  To  retrieve
       the  alignment  required  for  specific instance of pmem2_source** use pmem2_source_alignment(3).  By de‐
