NAME

       semanage_modify - SELinux Management API

SYNOPSIS

       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

       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

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