Hello
I would like copying bits from a CFMutableDataRef to another.
L_cnt bits starting in H_i at L_adi, to H_j starting in L_adj
That's how I perform this :
procedure f_HBlockToHBlock (H_i, H_j: CFMutableDataRef; L_adi, L_adj, L_cnt: SInt32);
var
h_buf: CFMutableDataRef;
h_xx_buf: UnivPtr;
begin
h_buf := CFDataCreateMutable(nil, L_cnt);
if h_buf <> nil then
begin
h_xx_buf := CFDataGetMutableBytePtr(h_buf);
CFDataGetBytes(H_i, CFRangeMake(L_adi, L_cnt), h_xx_buf);
CFDataReplaceBytes(H_j, CFRangeMake(L_adj, L_cnt), h_xx_buf, L_cnt);
CFRelease(h_buf)
end
end;
Well… I'm sure there is a simpler way (whithout having to create h-buf)
Any idea ?
