if i want to "Delete", or not write the first 4 characters of a memory block... how do i do so?

heres some sample code

in.open ("C:\\moviecopy.wmv", ios::binary );
in.seekg (0, ios::end);

length = in.tellg();

in.seekg (0, ios::beg);

buffer = new char [length];

in.read (buffer,length);
in.close();

out.open("C:\\moviecopyfix.wmv");
out.write(buffer,length);
out.close();

i want to take out the first four characters in this binary memory block... please help

out.write(buffer+4,length-4);

thats not working for me... its adding 15 bytes (bits?) of info every time i open and re write no matter what.

Maybe you need to add ios::binary to your 2nd open call:

out.open("C:\\moviecopyfix.wmv", ios::binary);
