assigning values to a dynamically allocated array of structures

Hi,
I am trying to dynamically create an array of structures of type page. The page struct looks like this:

Code:

---

typedef struct
{
  unsigned short int proc_no;
  unsigned short int page_no;
} page;

---

Then in a function called set_trace, I am using malloc to dynamically create the array. I believe thus far my code is correct, but the next thing I'm trying to do is enter values into this array of structs. This is what my set_trace function looks like.

Code:

---

void set_trace( unsigned short int proc_no, unsigned short int trace[], page *pPter  )
{
  pPter = malloc( sizeof( page ) * trace_size );
  for( int n = 0; n <= trace_size; n++ )
  {
      pPter.process_number = proc_no;
      pPter.page_number = trace[n];
  }
}

---

For each iteration of the loop, I am trying to assign the proc_no and the value at trace[n] to the nth page in the array. Can someone show me how to do this?

You need to pick a structure first out of your array to assign in to, and then assign it:

Code:

---

pPter[n].process_number = proc_no;
pPter[n].page_number = trace[n];

---

Note that you are trashing memory because your for-loop takes one too many steps.

thanks!
