C++ Error Lnk2019 Unresolved External Symbol
unresolved external symbol _snprintf In the stdio.h I cannot see the _snprintf declaration. Is _snprintf missing in VC++ 2008?

This works fine in VS2008, I would suggest you try it in Express Edition as well (I don't have Express to test it). c:\TEMP>type test.cpp #include

The project works fine with cygwin. I had to add _CRT_SECURE_NO_WARNINGS to preprocessor settings to get this far, but i don't think that has a influence. Here is the named function: #include
