The following query function is supported for any semanage record.
Replace the function and object name as necessary.
extern int QUERY_FUNCTION (semanage_handle_t *handle,const semanage_OBJECT_key_t *key,semanage_OBJECT_t **response);
The query function will fail if a matching key is not found.
Otherwise, the corresponding object is returned.
The handle is used to track persistent state across semanage
calls, and for error reporting. The key identifies the object
being queried, which will be stored in the address pointed by
response The key is a property of the caller, and will not be
stored or modified internally. The object returned becomes a
property of the caller, and must be freed with
This function requires an semanage connection to be
established (see semanage_connect(3) )
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.
