Use at your own risk. -LPSM DATABASES ARE NOT PORTABLE. This is pretty much inherent in the -fact that the LPSM library does not attach any meaning to the data it -stores. Therefore it is imperative that your application allows a way -to dump its database contents in a portable form. - -Currently the persistent memory database is not sharable nor -thread-safe. I'm hoping to resolve at least the latter condition in -due time. - -Because the persistent memory is mapped into memory at a fixed address -(which varies with architecture) it is not possible to have more than -one LPSM database mapped at any one time. - - -** Functionality description: - -The persistent memory store can be used in two modes: managed and -unmanaged. Unmanaged provides a flat chunk (arena) of memory without -any further management support; managed provides management via -malloc/free/realloc. - -All of these use a pair of files as backing store: a datafile, which -is equivalent in size to the managed memory, and a logfile, which is -used for the commit log. - -The LPSM library installs a signal handler for SIGSEGV. - -Please see the following man pages included with this distribution: - -Unmanaged mode: - - lpsm_arena_init(3) - lpsm_checkpoint(3) - lpsm_extend(3) - lpsm_shutdown(3) - lpsm_recover(3) - -Managed mode: - - lpsm_init(3) - lpsm_recover(3) - lpsm_checkpoint(3) - lpsm_shutdown(3) - lpsm_malloc(3) - lpsm_arena_stats(3) - lpsm_recover(3) +Please see the included man page lpsm(7) for usage details. |
