c - Max size of pointer array to 2D array? -

i'm using following allow me choose 2d array use, dynamically.

const prog_uint16_t (*p)[8]; p = arrayname; 

this works fine 2d array of size [3][8], require [10][1025].
when try this:

const prog_uint16_t (*p)[1025]; p = arrayname; 

i "cannot convert" error.

any ideas? thanks!

edit:

here's declaration of 2d array works. 1 doesn't declared same way, different number of entries ([10][1025]).

const prog_uint16_t tri[3][8]={{10,20,30,40,50,60,70,80},{11,21,31,41,51,61,71,81},{12,22,32,42,52,62,72,82}}; 

thanks!

you cant change size , type of constant pointer of course can change data pointed or

else cant resize type ofp pointer

look code maybe you

const int x;             // x cannot modified  const int* px = &x;      // px address of const int                  // , can't used change int   *px = 4;                 // illegal - can't use px change int   int* pint;       // address of normal int    pint = px;       // illegal - cannot convert const int* int* 

be successfull
