RE: Standard calling convention on Windows?

["King, Mike" <MKing@...>]

The default is __cdecl.

I'm now thinking "a C project" in C++Builder 2009 isn't really a C project.  The following page shows the prefix is added or not added depending on the linkage.

Your compiler's default calling convention?

Microsoft Visual C++ creates projects with __cdecl as the default
calling convention (or at least recent versions do), though I cannot
speak for other compilers.
