The unanimous reply was to use signal() library. It contains various
routineslike sigprocmask(), sigemptyset(),sigfillset(), sigaddset(),
sigdelset(),sigismember(), sigaction() etc to do such rudimentary things.
Some people have advised to use 'trap' command in the parent process which
runs this C program. Another very good suggestion was to use 'stty raw'
command in the parent process.
My apologies to those who thought that my question was off-topic. I will be
careful in future.
Thanks & Regards
John Black

My original Mail:
Hi,
I am writing a C program which contains something like this:
-----------------------------------------
printf("\t\t\t\tA- Archie\n");
printf("\t\t\t\tN- Finger\n");
printf("\n\n\n\t\t\tEnter Your Choice (A or F)");
scanf("%c",&x);
if (x == 'A')
{
system("/usr/bin/archie");
printf("\n\t\t\tPress Any Key To Continue");
scanf("%c",&y);
}
else if (x == 'N')
{
system("/usr/bin/finger");
scanf("%c",&y);
printf("\n\t\t\tPress Any Key To Continue");
scanf("%c",&y);
}
--------------------------------
I want to disable all the interrupts so that if some body presses Ctrl-D or
Ctrl-C to stop the execution of this program then he does not succeed.
I am compiling this program of solaris 2.5 using gcc.
Thanks in advance. I will summarize.
J. Black
