NAME         top

       semanage_query - SELinux Management API

SYNOPSIS         top

       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);

DESCRIPTION         top

       Behavior:
              The query function will fail if a matching key is not found.
              Otherwise, the corresponding object is returned.

       Parameters:
              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
              semanage_OBJECT_free.

       Requirements:
              This function requires an semanage connection to be
              established (see semanage_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.
