DbgLog

The DbgLog macro sends a string to the debug output location, if logging is enabled for the specified type and level. This macro is ignored in retail builds.

Syntax

  void DbgLog((
    DWORD Types,
    DWORD Level,
    const TCHAR *pFormat,
    ...
));

Parameters

Types

Bitwise combination of one or more message types.

Level

Logging level for this message.

pFormat

A printf-style format string.

...

Additional arguments for the format string.

Remarks

If debug logging for any of the message types is set to the specified level or higher, this macro sends the formatted string to the debug output location.

The macro automatically adds a newline character to the output string.

Example

DbgLog((LOG_TRACE, 3, TEXT("Connected input pin %d"), nPinNumber));

Note the additional set of parentheses that must enclose the macro parameters.

Requirements

**  Header:** Declared in Wxdebug.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
