It should "just work". Simply make sure to follow the usual rules for calling into C++ code from C and vice versa: - Use "extern C" linkage for all functions that must be accessible by dlopen(), and preferably also for any functions that you might take a function pointer to and pass to C code - Never return new()'d memory that might be free()'d by the C code; use malloc() - Never delete() memory that was malloc()'d by the C code; use free() - Never let an exception propagate into the C code; use a catch-all block at the top level of all "extern C" functions ... and probably other things I've missed. -- Craig Ringer -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
