I finally got to work and developed MTK in C.

 

UseC LanguageSimulate C ++ encapsulation.

Typedef struct Test

{

Int Info;

Char * pbuff;

INT (* getinfo) (struct test * pthis); // in C ++, each member function will have a this pointer, exceptProgramThe Member is transparent and does not have this pointer in the structure of the C language. Therefore, we do this ourselves;

Void (* inittest) (struct test * pthis); // equivalent to the constructor

Void (* dtor_test) (struct test * pthis); // destructor.

} Testsample;

 

// Finally implement the inittest () function so that compilation can be completed.

Void getinfo (struct test * pthis)

{

Return pthis-> Info; // and multi-image of C ++ ..

}

 

Void inittest (struct test * pthis)

{

Pthis-> getinfo = getinfo; // The initialization function must be at the end.

Pthis-> pbuf = (char *) malloc (102 * sizeof (char ));

Pthis-> info = 0;

}

 

Void dtor_test (struct test * pthis)

{

If (pthis! = NULL)

{

Free (pthis );

}

}

 

# Include <stdio. h>

Int main ()

{

Testsample test;

Test. inittest (& Test); // This pointer must be passed manually every time ...... trouble.

Test. getinfo (& Test); // This is passed implicitly in the C ++ member function.

Test. dtortest (& Test );//

Return 0;

}
