pure virtual function

基本解釋

The code generated for the pure virtual function is shown in Listing 1.
爲(wèi)純虛函數(shù)所生成的代碼如列表 1 中所示。
For example, to create a pure virtual function such as virtual int purevirtualop(int x)=0, perform these steps
擧例來說，創(chuàng)建一個(gè)純虛函數(shù)：virtual int purevirtualop(int x)=0，請執(zhí)行如下這些操作
After loading the DLL, the EXE calls an exported C function in the DLL, which returns a pointer to a pure virtual interface.
加載 DLL 後，EXE 便調(diào)用 DLL 中輸出的 C 函數(shù)，該函數(shù)返廻一個(gè)純虛擬接口指針。
