All of the Win32 APIs known to Wine are listed in the .spec file of
their corresponding dll. An unimplemented call will look like (from
gdi32.spec)
269 stub PolyBezierTo
@ stub PolyPatBlt
To implement this call, you need to do the following four things.
1. Find the appropriate parameters for the call, and add a prototype to
the correct header file. In this case, that means [include/wingdi.h],
and it might look like
BOOL WINAPI PolyBezierTo(HDC, LPCVOID, DWORD);
BOOL WINAPI PolyPatBlt(HDC, LPCVOID, DWORD);
If the function has both an ASCII and a Unicode version, you need to
define both and add a #define WINELIB_NAME_AW declaration. See below
for discussion of function naming conventions.

is 32-bits. However, the relay code handles pointers and pointers to
strings slightly differently, so you should use 'str' and 'wstr' for
strings, 'ptr' for other pointer types, and 'long' for everything else.

The 'PolyBezierTo' at the end of the line is which Wine function to use

The 'PolyPatBlt' at the end of the line is which Wine function to use
for the implementation.
3. Implement the function as a stub. Once you add the function to the .spec
file, you must add the function to the Wine source before it will link.
