Set environment variable DISPLAY to a proper value in your text terminal. This will solve your problem. The command will be as follows, export DISPLAY=host_ip_where_display_is_needed:0.0
you can use setenv() function to set this value from your c code.
Thanx boss... it worked !!!!! You solved a big problem... I got stuck on it since last three huors !!!! Thanx again !!!!
