D - A Bit of Help

reply Rick Clark <rickclark58 grandecom.net> writes:
I am trying to learn D and I thought I would convert some C programs 
over to D. One of them uses some console functions out of conio. I made 
a conio.d with the declarations the program uses and the program 
compiles fine, but does not link. Obviously, I am doing something wrong. 
Here is the error:

test1.obj(test1)
  Error 42: Symbol Undefined _SetConsoleCursorPosition 12
test1.obj(test1)
  Error 42: Symbol Undefined _FillConsoleOutputCharacter 24
test1.obj(test1)
  Error 42: Symbol Undefined _FillConsoleOutputAttribute 24
--- errorlevel 3

I tried compiling both the test program and conio (and windows.d too, 
just for grins) but I get the same error during linking. The C program 
compiles-links fine using DMC. If someone could point me in the right 
direction I would appreciate it.

Thanks for helping a novice. :)

Here is the silly little C program I am trying to convert to D. The 
console functions are what I am after: positon the cursor in the 
console, write different colors and clear the console screen. These 
might already be in the language, but I couldn't find them.

Thanks!

Those aren't the proper signatures for those symbols. I get: _SetConsoleCursorPosition 8 _FillConsoleOutputCharacterW 20 _FillConsoleOutputAttribute 20 So you should be importing them using: extern (Windows) { BOOL SetConsoleCursorPosition (HANDLE, COORD); BOOL FillConsoleOutputCharacterW (HANDLE, WCHAR, DWORD, COORD, LPDWORD); BOOL FillConsoleOutputAttribute (HANDLE, WORD, DWORD, COORD, LPDWORD); }

Thanks Burton, I'll give it a try.
