How to store argv[x] in my program???
Hi friends,
I have this problem that I am facing, I want to store an argument which is passed to main, and I want to store it as an array of characters. I can store number arguments with the help of x = atoi(argv[1]). Now suppose I passed the argument
Code:
Hello

to main, how can I store it somewhere in my program? I can access that "hello" through
Code:
argv[1]

but how can I store it in another variable, so that I can carry different operations on it? What can kind of variable is able to hold the value of
Code:
argv[1]

And is it only the SPACE character which seperates different arguments passed to the main, or is there any other character other than space which can act as seperator?
Looking forward to your wonderful replies.

Thanks in advance!

NAME

       pktool - manage softtoken object storage

SYNOPSIS

       pktool setpin

DESCRIPTION

       The pktool command allows users to manage the softtoken object store.

       The setpin subcommand changes the passphrase used to authenticate a user to the softtoken object store. setpin prompts the user for the old
       passphrase, if any. If the old passphrase matches, pktool prompts for the new passphrase twice. If the two entries of  the  new	passphrase
       match, it will become the current passphrase for the token.

       Passphrases may be any string of characters with lengths between 1 and 256 with no nulls.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred.

       ${HOME}/.sunw/pkcs11_softtoken

	   The user's default token object store.

       ${SOFTTOKEN_DIR}/pkcs11_softtoken
