#include "base/defs.h"
// This class is an encapsulation of a simple error-handling
// mechanism. The Warning and Fatal methods accept parameters in the
// same style as printf does; thus, for example, a user of this class
// may say:
// \par{\small \begin{verbatim}
// CL_Error::Warning ("Bad array bound %d limit %d", i, n);
//\end{verbatim}
// }\par
// The Warning method formats the string, and then invokes the warning
// handler with the formatted string. The default warning handler
// simply prints out the message.
//
// The Fatal handler behaves similarly; it invokes the fatal-error
// handler, and exits the program if the latter returns TRUE.
//
// The SetWarningHandler and SetFatalHandler methods can be used to
// provide user-specific warning and fatal handlers instead of the
// default ones. These methods return the previous values for their handlers.
typedef bool (*CL_ErrorHandler) (const char* message);

public:

// Issue a warning message, using the current warning handler.

static CL_ErrorHandler SetFatalErrorHandler (CL_ErrorHandler handler);
