Would anyone be so kind as to let me know if my function is flawed in some way and is causing the problem (such as memory leak etc...)
An example usage is...

Code:
string command = split_string(data, ",", 0);

It's not possible to answer that question until the innards of the string typedef are known. What are its member elements? Maybe all you need is a bigger buffer.

rwall

rwall(1M)						  System Administration Commands						 rwall(1M)

NAME

       rwall - write to all users over a network

SYNOPSIS

       /usr/sbin/rwall hostname...

       /usr/sbin/rwall -n netgroup...

       /usr/sbin/rwall -h hostname -n netgroup

DESCRIPTION

       rwall reads a message from standard input until EOF. It then sends this message, preceded by the line:

		Broadcast Message ...

       to all users logged in on the specified host machines. With the -n option, it sends to the specified network groups.

OPTIONS

       -n netgroup     Send the broadcast message to the specified network groups.

       -h hostname     Specify the hostname, the name of the host machine.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWrcmdc 		   |
       +-----------------------------+-----------------------------+

SEE ALSO

       inetd(1M), listen(1M), pmadm(1M), sacadm(1M), wall(1M), attributes(5)

NOTES

       The  timeout is fairly short to allow transmission to a large group of machines (some of which may be down) in a reasonable amount of time.
       Thus the message may not get through to a heavily loaded machine.
