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.
