NAME        top

       semanage_iterate - SELinux Management API

SYNOPSIS        top

       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        top

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 - usesemanage_OBJECT_cloneif 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 (seesemanage_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:              Thehandle is used to track persistent state across              semanage calls, and for error reporting. Thehandler is the              function to execute, withhandler_arg as its second              parameter, and each object as its first parameter.Requirements:              This function requires an semanage connection to be              established (seesemanage_connect(3) )

RETURN VALUE        top

       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.
