Thread: getopt question

if I want to specify that the user must specify -p x, then is the following code valid?
is there a way to do that using the getopt? in other words if they don't specify it then an error occurs...
or do I need to do that manually

Code:

getopt(argc, argv, "w:h:t:p:")

you should check up on getopt() I think fifth down the list might be what you're looking for.

so doing:

Code:

getopt(argc, argv, "w::h::t::p:" )

is the same as saying that -w -h and -t are optional but -p are required?

however when I do that it gives me a seg fault

well i'd take out the smiley face for starters then i'd try taking out that extra semi-colon.
