C++ (Cpp) _openDevice Examples

Example #1

File: MeterSML.cpp Project: mysmartgrid/vzlogger

int MeterSML::open() {
	
	if (_device != "") {
		_fd = _openDevice(&_old_tio, _baudrate);
	}
	else if (_host != "") {
		char *addr = strdup(host());
		const char *node = strsep(&addr, ":");
		const char *service = strsep(&addr, ":");
		if(node == NULL && service == NULL) return -1;
		_fd = _openSocket(node, service);
		free(addr);
	}
	return _fd;
