My own argv with some modifications

I am trying to write my own type of argv that puts arguments into a an array, commands[]. I want to use this in a menu shell in a program. An example:

shell> create “an message with spaces”

When typing this in the menu the command array should have length 2.

command[0] = create
command[1] = an message with spaces

Sow when we have a sentences between “ and “ the code wont distinguish(create an new array element) when we have a space.

How can we do that ?

Code:

	while (fgets(line, LINE_MAX, stdin) != NULL) {
	    command = line;

	}

This code will read a line from the terminal, but how can I put the sentences in a array?

Depending on the OS... you may have to quote them.

In windows My name is fred is interpreted as
My
name
is
fred

If you put it in quotes it will see it as
"My name is fred"... all once sentence.

Of course you'll have to remove the quotes after copying it from your command line to the array.

You put them in your array with strcpy() or similar. You're trying to copy a string, C doesn't know strings... so you need the library's string handlers to help you.

Thank you

I use unix. I need some code to se how I can divide a sentence after spaces and taking care of quotes ?

Yes you could spend your time looking for code and examples but if you really want to understand the language and it's power, you really should try to figure this out on your own as much as you can. Hit the man pages for your compiler, read a book (they do still make them, you know), grab a couple of tutorials... In the end you'll be glad you did.

For now look up strtok() and memset()
