NAME         top

       semanage_modify - SELinux Management API

SYNOPSIS         top

       The following modify function is supported for any semanage
       record.
       Replace the function and object name as necessary.

       extern int MODIFY_FUNCTION (
            semanage_handle_t *handle,
            const semanage_OBJECT_key_t *key,
            const semanage_OBJECT_t *data);

DESCRIPTION         top

       Behavior:
              If a matching key is found in the local store, the provided
              object will replace the current one. Otherwise, it will be
              added to the store. When semanage_commit(3) is invoked,
              changes will be permanently written into the local store,
              and then loaded into policy. Validity of the object being
              added is checked at commit time. Adding new objects with
              respect to policy is allowed, except in the case of
              booleans. Attempt to add new booleans with respect to
              policy will fail at commit time.

       Parameters:
              The handle is used to track persistent state across
              semanage calls, and for error reporting. The key identifies
              the data object, which will be written into the store. The
              key are data are properties of the caller, and are not
              stored or modified internally.

       Requirements:
              This function requires an semanage connection to be
              established (see semanage_connect(3) ), and must be
              executed in a transaction (see
              semanage_begin_transaction(3) ).

RETURN VALUE         top

       In case of failure, -1 is returned, and the semanage error
       callback is invoked, describing the error.  Otherwise 0 is
       returned.
