The information in this article applies to:

SUMMARY
=======
Microsoft CodeView versions 4.0 and later, which support debugging C++ programs,
do not correctly evaluate functions that use default arguments. When an
expression is used that requires CodeView to evaluate a function with a default
argument, the following error message is displayed:
CXX0047: Error: argument list does not match a function
MORE INFORMATION
================
The sample code below contains a function that has a default argument. In the
program, the function PrintOut() can be called either with a void parameter list
or with a character pointer. When the following command is executed from
CodeView's command window
? PrintOut("This is a string constant")
the function is called and "This is a string constant" is printed to the output
screen. When the function PrintOut() is called with no parameters, for example
? PrintOut()
the error CXX0047 is generated. This occurs only when using the "?" command in
CodeView to force a function to be evaluated.
Default arguments are supported only in C++ programs.
Sample Code
-----------
/* Compile options needed: /Od /Zi
*/
#include <iostream.h>
void PrintOut (char *String = "This is a default argument.");
void main (void)
{
PrintOut();
PrintOut( "This is not a default argument.");
}
void PrintOut (char *String)
{
cout << String << endl;
}
