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.
