|
|
* IDebugStream is a stream to be used for debug output. One
|
|
* implementation uses the OutputDebugString function of Windows.
|
|
*
|
|
* The style is modeled on that of AT&T streams, and so uses
|
|
* overloaded operators. You can write to a stream in the
|
|
* following ways:
|
|
*
|
|
* *pdbstm << pUnk; // calls the IDebug::Dump function to
|
|
* display the object, if IDebug is supported.
|
|
* int n;
|
|
* *pdbstm << n; // writes n in decimal
|
|
*
|
|
-
|
|
* *pdbstm << sz; // writes a string
|
|
*
|
|
* CBool b(TRUE);
|
|
* *pdbstm << b; // writes True or False
|
|
*
|
|
* void FAR * pv;
|
|
* *pdbstm << pv; // writes the address pv in hex
|
|
*
|
|
* TCHAR ch;
|
|
* *pdbstm << ch; // writes the character
|
|
*
|
|
* ATOM atom;
|
|
* *pdbstm << CAtom(atom); // writes the string extracted from the atom
|
|
*
|
|
* HWND hwnd;
|
|
* *pdbstm << CHwnd(hwnd); // writes the info about a window handle
|
|
*
|
|
* These can be chained together, as such (somewhat artificial
|
|
* example):
|
|
*
|
|
* REFCLSID rclsid;
|
|
* pUnk->GetClass(&rclsid);
|
|
* *pdbstm << rclsid << " at " << (void FAR *)pUnk <<':' << pUnk;
|
|
*
|
|
* This produces something like:
|
|
*
|
|
* CFoo at A7360008: <description of object>
|
|
*
|
|
* The other useful feature is the Indent and UnIndent functions
|
|
* which allow an object to print some information, indent, print
|
|
* the info on its member objects, and unindent. This gives
|
|
* nicely formatted output.
|
|
*
|
|
* WARNING: do not (while implementing Dump) write
|
|
*
|
|
* *pdbstm << pUnkOuter
|
|
*
|
|
* since this will do a QueryInterface for IDebug, and start
|
|
* recursing! It is acceptable to write
|
|
*
|
|
* *pdbstm << (VOID FAR *)pUnkOuter
|
|
*
|
|
* as this will simply write the address of pUnkOuter.
