第 24 章 擴充與內嵌標準型的 Python
內嵌 Python
如果你已經有一個以 C 或 C++（或其他典型的編譯語言）撰寫的應用程
式，你可能會想要內嵌 Python 作為你應用程式的指令稿語言（scripting
language）。要在 C 以外的語言中內嵌 Python，那個其他的語言必須能夠
呼叫 C 函式（你要如何那樣做，會隨著情況而變，不只是依據語言，還取
決於特定的語言實作：用的是什麼編譯器、什麼連結器等等）。接下來，
我們涵蓋 C 的觀點，其他語言，則如前面提到的，很大程度上取決於為了
從它們呼叫 C 函式，你必須做些什麼。
安裝常駐的擴充模組
為了讓 Python 指令稿與你的應用程式溝通，你的應用程式必須提供帶
有 Python 可取用的函式和類別的擴充模組，以對外提供你應用程式的功
能性。若是，如同一般情況，這些模組連結至你的應用程式（而非位在
Python 可在必要時載入的動態程式庫中），就呼叫
PyImport_AppendInittab
C API 函式向 Python 註冊你的模組為額外的內建模組：
PyImport_AppendInittab int PyImport_AppendInittab(char*
name,void (*initfunc)(void))
name
是模組名稱，Python 指令稿會用它來匯入該模組。
initfunc
是模組的初始化函式，不取引數，也不回傳結果，如
前面「初始化模組」中所涵蓋的（也就是說，
initfunc
是模組
的函式 ...
