If somebody else have some idea, please post it asap.

Hello david,
I have attached the test program as you asked for testing
"sigtimedwait".whether it returns proper "si_fd" value.
Please try with this.

 I have tested by the following way:
 1)Compiled and run the program
 2)In the other terminal, i have run the command "telnet localhost 5001".
 3)You can view the results in the terminal where the test program is
 running.

 Thanks in advance.
 Kumar.
