thanks so much for your help. I will check it out.
I have been progaming for a long time in fortran, PL/M, c, c++,perl but
there is always more to learn, great!
I should try this under windows instead of linux and see what happens.
Thanks Eitan.
I have also downloaded the Expect modules and check that out.
Cheers,
Rob Key

The C programme looks like this (very simple)
#include<stdio.h>
int main()
{
int i;
char s[20] = "hello from c";
for (i = 0; i< 15; i++) {
sleep(1);
printf("%s %d\n", s, i);
}
return 0;
}
and yet I only get the output to perl when it is finished and died.
Thanks,
You get multiple levels of output buffering:
1) C does its own output buffering. Take a look at man setvbuf(1)
2) The operating system buffer which is entirely different than the C buffer
You need to disable both of them to get fully unbuffered output
