About usage of command line arguments in another function defined out of main func

[shylaja1]

Hi,

How do i use command line arguments in the function which is called in main function and defined outside the main function.Even though,i can pass them as arguments..but if i do that...it makes me to pass many arguments.So,pl ease let me know how do i fetch the cmnd line arguments in another function without passing them as parameters to the function.

You could implement a global singleton object that holds a copy of the command
line arguments. The first thing a main() function should do is create such a single
instance. All other functions can access the instance for the value(s) of the
command line arguments.

The prototype for the main function is

int main( int argc, char *argv[]);

You can pass argc and argv to any function called from main. That's only two parameters to pass.

Hi ,
the compiler gives error telling that unknowv variable..argv in the function defined out of main or which is called out frm main...Plz can u implement a prgrm..with the help of pointers.

Please show me
... the function prototype for the function you're trying to pass the command line arguments to.
... your function main definition (the first line of the function; the one that looks like a prototype).
... the line from within main where you call that function and pass it the command line arguments.

Make sure the prototype line occurs before the definition of the main function.

Compiles on my machine. What then?

ip2oct =int(*(++argv)) ;

I guess what it is supposed to do, but it clearly does in wrong. You advance argv to next argument string ( if it exist ), take first character of it (e.g. '1', 49 decimal and convert to unsigned char, 49?

Is this the first time you've tried to acquire and parse the command line arguments? If so, then you should concentrate on that portion of the code -- strip away everything else.
