Example:

	Copy Code
AT_ERRCOUNT errCount = 0 ; HIG_REC_APPROX_REGEX higRecApproxRegex = 0 ; LPFNIG_REC_APPROX_REGEX_MATCH_CB user_callback = 0; LPVOID user_data = 0 ; IG_REC_approx_regex_create( &higRecApproxRegex ) ; errCount = IG_REC_approx_regex_match_cb_get ( higRecApproxRegex, &user_callback, &user_data ) ; IG_REC_approx_regex_delete( higRecApproxRegex ) ;
