specifying a prototype


Hi,

suppose i want to say my function will return the base address of an array of type T, my prototype will look like this

T (*) [] getRowAddress();

I'am using templates so T will have appropriate data type

i believe when i declare a pointer to an row of integers (array), i will use

int (*a) [n];

Going by this, my function prototyping should be correct. Please correct me if I'am wrong.

Thanks,

Why not just use
Code:
T *foo1();
if you want to return a pointer to the first index of an array, and
Code:
T **foo2();
if you want to return a pointer to the pointer to the first index of an array.

I guess these would look something like:
Code:
T *foo(){
    int x[5];
return(x);
}

T **foo2(){
    int x[5];
return(&x);
}
respectively.

I think you are making this all more complicated than it need be.

good luck
