On assignment to a function pointer

[Sayan Mukherjee]

Hi,

I have a the following declarations in my C code:

void func1(void);    // Prototype of function func1()

long *p = ...        // pointer to long which contains a valid address.
                     // The address is that of the function func1()
                     
void (*fptr)(void);  // This is the function pointer 

This address in 'p' is, as stated above, the address of the function func1().

How do I assign from pointer 'p' to pointer 'fptr' so that the
function executes if called as given below:

fptr(); 

Thanks in advance.
