Example

The following example shows how to retrieve environment variables with lrt functions. The lrt_tuxgetenv function retrieves the value of the NLSPATH variable.

// set the server address
lrt_tuxputenv("WSNADDR=//server:65535");                                                                        
// find out what which natural language used.
lrt_tuxgetenv("NLSPATH");                                                    
// use default settings to get environment information.
lrt_tuxreadenv(NULL, NULL);
