| Summary |
#include <net_config.h> U8* http_get_lang (void); | |
| Description | The http_get_lang function retrieves the preferred language setting from the browser. You can use this information to implement automatic language selection for your embedded web pages. The http_get_lang function is a system function that is in the RL-TCPnet library. The prototype is defined in net_config.h. Note
| |
| Return Value | The http_get_lang function returns a pointer to the language code, which is a null-terminated string. | |
