    Command:

    semanage_port_iterate_local

    
    
    
    

    SYNOPSIS

           The following iterate function is supported for any semanage record.
           Replace the function and object name as necessary.
    
           extern int ITERATE_FUNCTION (
                semanage_handle_t *handle,
                int (*handler) (
                              const semanage_OBJECT_t *object,
                              void *varg),
                void *handler_arg);
    
    
    

    DESCRIPTION

           Behavior:
                  The iterate function will execute the specified handler over all
                  objects in the selected location. An arbitrary argument  can  be
                  passed into the handler function along with each object.
    
                  The object passed in is property of the libsemanage library, and
                  may not be modified or preserved - use semanage_OBJECT_clone  if
                  that is necessary.
    
                  The  handler code may not invoke any semanage write requests for
                  the same object type (i.e. modifying the underlying store is not
                  allowed).  The iterate function is reentrant only while inside a
                  transaction (see semanage_begin_transaction ). It is not safe to
                  execute  other semanage read or write requests within iterate if
                  not inside a transaction. The handler may return  -1  to  signal
                  error  exit,  0  to  signal continue, and 1 to signal successful
                  exit early (the iterate function will stop accordingly).
    
           Parameters:
                  The handle is used to track  persistent  state  across  semanage
                  calls,  and  for error reporting. The handler is the function to
                  execute, with handler_arg as  its  second  parameter,  and  each
                  object as its first parameter.
    
           Requirements:
                  This  function requires an semanage connection to be established
                  (see semanage_connect(3) )
    
    
    

    RETURN VALUE

           In case of failure, -1 is returned, and the semanage error callback  is
           invoked,  describing  the  error.   Otherwise a non-negative integer is
           returned (a commit number). The same number will  be  returned  by  all
           other semanage object read calls until the next commit.
