COM(LLVM)
COM（Component Object Model）はマイクロソフトの提唱するプログラム部品の仕様である。
COM を用いて開発された部品であれば言語を問わず利用することができる。

COM(Objective-C)
COM（Component Object Model）はマイクロソフトの提唱するプログラム部品の仕様である。
COM を用いて開発された部品であれば言語を問わず利用することができる。
以下は MinGW 版 Objective-C による COM クライアントの例となっている。ソースコード

Hello, Win32 API(GAS) World!
Posted on 3月 14th, 2013 by cx20
Win32 API(GAS)
Win32 API は、Windows の機能にアクセスする為の API（Application Programming Interface）である。
以下は GAS からの呼出し例である。ソースコード（GAS）
.file "hello.c" .def ___main; .scl 2; .type 32; .endef .section .rdata,"dr" LC0: .ascii "Hello, World!
上記コードは、下記の C のソースを MinGW版 GCC にてアセンブリコード出力（gcc -S hello.c）したものである。
ソースコード（C言語）
#include <windows.h> int main( int argc, char* argv[] ) { MessageBox( NULL, "Hello, Win32 API World!", "Hello, World!", MB_OK ); return 0; }
コンパイル方法（MinGW版 gcc）
C:¥> gcc -c hello.s C:¥> gcc -o hello hello.o
