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. Whensemanage_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:              Thehandle is used to track persistent state across              semanage calls, and for error reporting. Thekey identifies              thedata 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 (seesemanage_connect(3) ), and must be              executed in a transaction (seesemanage_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.
