Hi, As far as I know, the compiler automatically allocates memory for the address where a pointer is saved. The unallocated part is the data attached to a pointer. What happens with a pointer to a pointer like void**? Does the compiler allocate memory for two addresses with the first one in the chain pointing to the second one? Does it allocate memory only for the first address?
What I can say about pointers: a) int * K ===> Address(preallocated) -------------------> integer [ not preallocated ] b) void** V ===> Address1 (preallocated) ------> Address2(preallocated) OR: void** V ===> Address1 (preallocated) -----> Address2(not preallocated) ? c) int **L ===> Address1 (preallocated) -----> Address2(allocated) -----> int (not allocated) OR int **L ===> Address1(preallocated) -----> Address2(not allocated) -----> int (not allocated) By 'preallocated' I mean the compiler will automatically generate code to allocate memory for the actual pointer not the data. d) Is this allowed: void***, int***, double***, etc? _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
