NAME

       semanage_query - SELinux Management API

SYNOPSIS

       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

       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

       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.
