I am involved in developing a program with the following specifications.(in Linux)
Whenever I use ftp to fetch a file(get <filename>) if I press Control-C the file should be saved upto that point in the file.I write a footer to the file about the file pointer position .When I try to fetch the same file using get the file should continue transfer from the point it was saved upto and thus the transfer should begin only after the point upto which it was saved.I can only modify the ftp client code.The program should work with existing ftp servers.How will I achieve this (i.e making server send data packets containing the file contents only after a particular byte offset instead of from beginning of the file).Please help me in this regard and also provide general advice on the problem.
