[C400-L] dynamic array of pointers

[James Rich <james@xxxxxxxxxxx>]

Hey everyone,

I need to make an array of pointers to struct that can be dynamically
resized.  Right now i have this:

typedef struct _screenfields
{
  unsigned int totalfields;
  field5250 fields[1782];
} screenfields;

screenfields *fields5250[10];

I need to make the fields5250 array be dynamic (instead of only 10
elements).  I think I need to do:

screenfields **fields5250;

I don't know how to do the malloc() properly for that, though.  Currently
for my static array of pointers I do this:

  fields5250[0] = (screenfields *) malloc (sizeof (screenfields));

Which works great.  I think I should be able to keep the same statement to
allocate each element using a dynamic array, but I don't know how to
allocate the array itself.  I think I don't have to allocate the array
itself at all, since the array is just a pointer to the first element in
the array.  But it's been seg faulting, so I think I'm doing something
wrong.
