SYNOPSIS

10       The following query function is supported for any semanage record.
11       Replace the function and object name as necessary.
12
13       extern int QUERY_FUNCTION (
14            semanage_handle_t *handle,
15            const semanage_OBJECT_key_t *key,
16            semanage_OBJECT_t **response);

DESCRIPTION

20       Behavior:
21              The  query  function  will  fail if a matching key is not found.
22              Otherwise, the corresponding object is returned.
23
24
25       Parameters:
26              The handle is used to track  persistent  state  across  semanage
27              calls,  and  for  error reporting. The key identifies the object
28              being queried, which will be stored in the  address  pointed  by
29              response  The  key  is a property of the caller, and will not be
30              stored or modified internally. The  object  returned  becomes  a
31              property   of   the  caller,  and  must  be  freed  with  seman‐
32              age_OBJECT_free.
33
34
35       Requirements:
36              This function requires an semanage connection to be  established
37              (see semanage_connect(3) )

39

RETURN VALUE

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