I am confuse on how to read the pointers copied in an array using memcpy. Following is what I have tried, but does not work. Basically, I have allocated block of memory in which I am copying pointers similar to array fashion, but during retrial it is not working. While this works with basic data types properly I want to store anything in the element block, It can be either integers or pointers . #include <stdio.h> #include <stdlib.h> #include <string.h> #define INDEX(x) ((char *)elements + (sizeof(int*) * (x))) int size = 10; void f2_int_ptr() { int i = 0; void *elements = (void*)malloc(size * sizeof(int*)); for ( i = 0; i < size; i++ ) { int *v = ( int *) malloc ( sizeof(int)); memcpy ( v, &i, sizeof ( int )); memcpy ( INDEX(i) , v, sizeof (int*)); } for ( i = 0; i < size; i++ ) { int *v = (int*)0; memcpy ( v, INDEX(i), sizeof(int *)); printf ( "%d\n", *v ); } } void f1_int() { int i = 0; void *elements = (void*)malloc(size * sizeof(int)); for ( i = 0; i < size; i++ ) { memcpy ( INDEX(i) , &i, sizeof (int)); } for ( i = 0; i < size; i++ ) { int v; memcpy ( &v, INDEX(i), sizeof ( int )); printf ( "%d\n", v ); } } int main(){ f1_int(); f2_int_ptr(); return 0; } In the above code f1_int works fine but f2_int_ptr does not work.
