Why don't you just set up file objects....the following example is from my old BG2 XP Patcher:

FILE *f = fopen("BGMain.exe","rb+wb");
FILE *f2 = fopen("VKXPPatcher.log","rb+wb");
fread(&d,8,1,f2);

location = (int)d;
fsetpos(f,&location);
fread(&e,4,1,f);

as you can see I open 2 files for binary read and binary write and then read into the address of the variable "d" 8 bits from the file f2. You can set the read position with fsetpos....those are C methods though, which would of course work in C++ but I guess you have to do it with C++ methods?
