Multiple File IO, Random Access.

Question

I was hoping someone could give me some code which outlines how to read records from two large files where there is no guarantee that the first file ends on a record boundary. (say record size is 1024 bytes, first file size 265289734 bytes and the second file is 4090 bytes and because the ram in my computer is only 256 MB I use a 64 MB buffer into which i read the file). I hope my description is easily understood and look forward to a reply.

Thanks in advance
Liam
