Otherwise it shall return -1 and set errno. ## Example ```c uint32_t to_sec; uint32_t to_usec; /* Save original timeout */ modbus_get_byte_timeout(ctx, &to_sec, &to_usec); ``` ## See also - [modbus_set_byte_timeout](modbus_set_byte_timeout.md) - [modbus_get_response_timeout](modbus_get_response_timeout.md) - [modbus_set_response_timeout](modbus_set_response_timeout.md)
