Programming Assignment #3 , Milestone HW3.C

Changes needed to be made to your ftpclient for milestone#3

• You should change the socket(AF_INET,...) calls in your code to mysocket().
• You should be using the interface in mysock.c rather than the system call socket interface. Thus you should prefix calls to connect, accept, bind, listen etc. by the word "my".
• The mysocket() function takes one argument (is_reliable). You should make sure your ftpclient allows an optional argument (-U) and if the user specifies this option, you should pass it appropriately to any mysocket() calls. If this argument is specified, it will always be immediately after the name of the program, i.e. it will always be in argv[1], if -U is specified at all. The remaining arguments remain the same.

Miscellaneous notes about milestone #3

• The output of ftpclient (i.e. either a simple OK message or an error) should remain the same as in previous assignment.
• If you use your version of ftpcopy for this part of the assignment, you should be able to just list your additional source files under "FTPCOPY_SRCS" in the provided Makefile.
