int pointer in class

Hello..
Im a little confused.. What would be the proper way to allocate memory for the new struct fd_array? And how should I check if its already allocate and relocate it? Should I use sockset *ns = new sockset.. ?

Thanks a lot

Code:

---

struct sockset {
        unsigned int fd_count;
        SOCKET *fd_array;
};

---

memory allocation in C++ is performed via the new operator. It
returns NULL if it fails. General form:

Code:

---

datatype *pointer;

if ((pointer = new datatype) == NULL)
    cout << "Alocation failed";

---

for arrays, it would be new datatype [size]

delete is used to free the memory, or []delete if an array was allocated to the pointer (no need to specify the size inside of [])

Code:

---

delete pointer;

---

There is no realloc equivalent in C++, so if you need to resize,
allocate new memory, copy the stuff from the old memory and
delete the old pointer.
