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.
