I have a prog that takes two parameters. The first one is a port and
the second is an integer that specifies the length of the string to 
be sent to this port.

If N=4 then I have to send a "\0\0\0\0" to the port. How can I write
a function that will take N as a parameter and return a string _out
(which consists of N "\0"s to my main(). 

And secondly what form of fprintf or fwrite do I use to print out the
string from the main. The function itself can handle the output of the
string if passing it as parameter is messsy. 

Thanks in advance
