+
+        mixed object_info(object ob, int what)
+
+DESCRIPTION
+        Returns some internal information about object <ob>. The
+        Argument <what> determines which information is returned.
+
+        It can be either a configuration option as given to
+        configure_object() or one of the following options:
+
+
+
+        Object Flags:

+
+        <what> == OI_RESET_STATE:
+           1 if <ob> is (still) reset, 0 else.

+
+        <what> == OI_LAMBDA_REFERENCED:
+           1 if <ob> has lambdas (and there replace_program()
+           is not allowed anymore), 0 else.

+        <what> == OI_SHARE_VARIABLES:
+           1 if clones of this program share their initial

+
+        <what> == OI_PROG_SWAPPED:

+
+        <what> == OI_VAR_SWAPPED:
+           1 if <ob>'s variables are swapped, 0 else.
+
+        <what> == OI_SWAP_NUM:
+           The swap number for <ob>s program, or -1 if not swapped.
+
+
+
+        Time Information:
+
+        <what> == OI_NEXT_RESET_TIME:
+            Time of the next reset.
+
+        <what> == OI_NEXT_CLEANUP_TIME:
+            Time of the next data cleanup.

+
+HISTORY
+        Introduced in LDMud 3.2.6.
+        Changes in LDMud 3.2.7:
+          - new basic result OIB_REPLACED.
+          - basic result OIB_IS_WIZARD is always 0 if set_is_wizard()
+              is not available.
+          - basic result OIB_APPROVED is gone.
+        LDMud 3.2.8 added OIM_DATA_SIZE to the result of OINFO_MEMORY.
+        LDMud 3.2.9 added the index mechanism, OIM_NUM_INCLUDES,
+          OIM_NO_INHERIT, OIM_NO_SHADOW, OIM_NO_CLONE, OIM_SIZE_STRINGS_DATA,
+          OIM_SIZE_STRINGS_TOTAL, and OIM_DATA_SIZE_TOTAL to the result
+          of OINFO_MEMORY.
+        LDMud 3.3.378 added the OIM_SHARE_VARIABLES to the result
+          of OINFO_MEMORY.
+        LDMud 3.3.654 added the OIB_NEXT_CLEANUP to the result of OINFO_BASIC.
+        LDMud 3.5.0 redesigned the whole efun.
