<h3>Windows & Linux Calling</h3>
|
|
|
|
<p>
|
|
As unfortunately both Windows and Linux have system and library calls with
|
|
as many as 10 parameters (for example <code>XCreateImage</code>),
|
|
a collection of calling thunks is required.
|
|
A single varidic thunk would be ideal, but is hard to do without per platform
|
|
assembly language.
