I found an old Smalltalk/V imagine from 2000 and tracked down how I was
able add calls to Windows DLLs and to add my own. It was in the class
DynamicLinkLibrary and its subclasses, e. g., a call to the GDIDLL to
draw a Bezier spline (which I believe I added) was:
bezierTo: hDC lpPoints: anLPPOINT count: anInt
<api: PolyBezierTo ulong struct ulong boolean>
^self invalidArgument
I added by own DLL to do matrix transformations that was written in
ASSEMBLER to optimized the floating point processor pipelining (a start
operation every cycle while it took 3 cycles to complete) and it
performed about 15% better.
I have not found anything similar in Pharo, but it must if external
libraries are used. NativeBoost seems to come close, but I cannot find
any documentation. Can someone point me to some documentation, code,
anything? It is greatly appreciated.
