@Poita_, ok, maybe you are right, but if somebody still wants to use 3-dimensional array allocated in one big chunk, here's how you add normal indexing to it:
void*** newarray(int icount, int jcount, int kcount, int type_size)
{
void*** iret = (void***)malloc(icount*sizeof(void***)+icount*jcount*sizeof(void**)+icount*jcount*kcount*type_size);
void** jret = (void**)(iret+icount);
char* kret = (char*)(jret+icount*jcount);
for(int i=0;i
