Say you have a struct.
struct my_c_struct {};
my_c_struct *ptr = 0; // uninitialised pointer
You need to prototype the function with a pointer to a pointer
void my_func(my_c_struct **pptr);
void my_func(my_c_struct **pptr)
{
*ptr = new my_c_struct;
if (!*ptr) printf ("error no memory\n");
else printf ("aye memory\n");
}
