how can I get the call __PRETTY_FUNCTION__ runing?

[Thomas]

Hello im using Visual Studio .net

And have troubel with the following line

ClassA::~ClassA ()
{
cerr<<__PRETTY_ FUNCTION__<<"\n "; \\this works with g++
}

on compiling I get this back:
filename.cc(20) : error C2065: '__PRETTY_FUNCT ION__' : undeclared identifier

does exist an library to add or have I just missed an command?
Thanks for your Help!

You have missed the fact that __PRETTY_FUNCTI ON__ is not part of
standard C++ and thus may not be available on every compiler.

__PRETTY_FUNCTI ON__ is not part of standard C++ but a g++ specific
extension. Consequently you cannot expect every compiler to support
this. If you are satisfied with just file name and line number you might
use a macro like this:

#define PRETTY_FUNCTION __FILE__":" << __LINE__

The predefined macro __FILE__ and __LINE__ are defined in the C++
standard, and should be available on any reasonable compilant C++
compiler. Note that this macro is not an exact equivalent for the
__PRETTY_FUNCTI ON__ macro; it only works for stream output. With a bit
more effort it can be modified to produce a string.
