SUMMARY
The standard output stream (cout) can be used in an application or Dynamic- Link Library (DLL) to display information. When using cout in an application and a DLL simultaneously, special care is needed to ensure that the text display is synchronized.
Because the cout text stream is buffered, text from a DLL may not appear correct relative to text from the application. To correct this problem, always use the endl manipulator when outputting text with cout. Below is an example:
cout << "Hello World" << endl;
The endl manipulator inserts a newline character and then flushes the stream buffer. This ensures that text displayed from the application and DLL is synchronized.
