I need help converting this "C++" DLL code to
straight "C", so it can compile with either LCC,
DevCpp, or the MinGW compiler.
Here's why:
This DLL code must NOT generate underscores
to work with the VDS scripting language. It
compiles under Borland C++ Builder 5, but using
"underscores off" kills many of the standard
C/C++ functions such as atoi, etc. (I can use
the VCL, but it bloats the DLL to 100k).
I have been told that LCC and GCC based compilers
do NOT generate underscores for straight C code,
but I haven't been able to convert this to
straight C.
Here's also a link to a zip file that contains
the CPP file, the compiled DLL file, and an
integrated EXE that runs it (so if ya convert it
to C and test it, you'll know what to expect):
http://www.trinex.net/users/mac/vdsfiles/test.zip
Everything is in this code (no other headers).
I have a similar Delphi example if that would
help anyone...

{
if(reason == DLL_PROCESS_ATTACH) // Runs this code when DLL has loaded...
{ MessageBox(NULL, "DLL Loaded", "TEST.DLL", MB_OK);
}

return 1;
