Running a executable in another process without creating a new process

Question

I want a write a program that run an executable image without creating a new process... I want to do this because I want to use plink that send a password to a remote ssh server...

The plink program sends the password provided in command line .. If I use fork and exec functions someone can see the password provided in command line using process explorer or ps -aef or cat /proc//cmdline .. How to avoid this security hole..and this program has to be run on both linux and windows ..

Set up your SSH server to use RSA public/private key authentication instead of passwords. This is usually a better choice anyway for SSH in general. See http://www.google.com/search?q=set+up+ssh+rsa.
