rsh in gtk program

[Rajesh Padalia <rpadalia qatar net qa>]

Hi List,
In my gtk1.2 program I need to run command on Solaris machine and wait
until
it finishes and then run rcp to copy files from Solaris machine. I am
trying following code. rsh does its job but my program stops. I tried
this
code with only rcp and it works fine. What exactly I need to do? 
Thanks in advance.
