Assigning functions to an array of function pointers

[RonInNYC]

I'm trying to create an array of function pointers and then assign compartilbe functions to them, so I can just call *pf[0](xxx);

The functions are all of the type

void func01(unsigned char*, int, int)

how would I create an array of function pointers and assign the address of the functions to them? So I could call them like

ptrToFunction[i](charBuffer, 10, 20);

I've read a bit on line and I thought I could do it but so far I've failed.

It seems trivial and I feel I'm close but close isn't good enough.


I'd like to assign the fuction addresses like this:
for (int i=0; i<10; i++)
if (i==1)
ptrToFunction[i]=func01;
if (i==2)
ptrToFunction[i]=func02;
etc. The actual logic is somewhat different than this but this close.

A function like this:

void func01(unsigned char*, int, int);
 

would have a function pointer like this:

void (*pf)(unsigned char*, int, int);

Therefore, an array of 10 of these pointers would be:

void (*pf[10])(unsigned char*, int, int);
 
 

Then you can:

pf[0] = func01;
 

and your call would be:

unsigned char ch = 0;
 
    pf[0](&ch,1,2);

Off you go.

I put this in the header file:
typedef
void (*pf[10])(unsigned char*, int, int);

and this in the cpp: (they are both class members)

for (int i=0; i<10; i++)
pf[i] = func01;

(ignoring that pf[i] will be assigned the same function address for all values of 'i'. However this caused errors:

error C3867: 'C::func01': function call missing argument list; use '&C::func01' to create a pointer to member

Removing the typedef, I still get:

error C2440: '=' : cannot convert from 'void (__thiscall C::* )(unsigned char *,int,int)' to 'void (__cdecl *)(unsigned char *,int,int)'
1> There is no context in which this conversion is possible

Actually, forget the array, as I'm making some more basic type of error. In the header file I have this:
void (*ptr)(BYTE*, int, int);

And in the implementation file I have this:

ptr=&func01;

OR
C::ptr=&C::func01;

etc. Still get errors

And this is the error I get:
error C2440: '=' : cannot convert from 'void (__thiscall C::* )(unsigned char *,int,int)' to 'void (__cdecl *)(unsigned char *,int,int)'
1> There is no context in which this conversion is possible

Firstly, this:

void (*ptr)(BYTE*, int, int);

should not be in a header file since this creates a pointer variable.
Secondly, this:

typedef
 void (*pf[10])(unsigned char*, int, int);
 

says that pf is a type. pf[10] cannot be a type since an array is not a typs is a collection f a type. Also, s typedef does not create a variable. You still need to create the array.

You say you are using a class now so you had better post your class declaration and the member function that getting the errors.
